Part of the problem here is that our definitions of "minimal" differ.
I do not consider The Wild Unknown to be minimal — not in the slightest. It is MODERN, yes. Minimal? No, not really. Same with the Mary-El. I would not at all consider the Mary-El to be minimal.
And no, I'm not talking about abstract, though there are decks that I would consider "minimal" that are *also* abstract, or use abstraction as a way of attaining minimalism. To a degree, that is exactly what I have done with the Orbifold: it is minimal, modern, and some could legitimately argue *also* abstract, too.
As for "new systems" I'd encourage you to find what is common among representations rather than what is different. Remember, too, that between the 20th century's main systems, there are definite discrepancies. Is the Thoth wrong if your point of reference is WST? Is Waite-Smith "wrong" when your reference is Thoth? No on both counts. They may not differ as much as some more modern decks might, but they are significantly different. Many modern decks have attempted to consolidate the two — The Wild Unknown to some extent being one of them; the Night Sun being another — and they have often managed to be successful because they have found some underpinning that is consistent between the two streams.
Since you keep coming back to the Mary-El, I'll stay with that example: yes, the image is totally different, but how different is the meaning really, and does it stray further away from the essence or move us closer to it? Breaking it down, Cups are about the subconscious, illusion and delusion, reflection, the interior world — not just "emotions" but the sensual inner state of feeling. Sevens are about individuality; about splitting apart from the pack, about separating from the community either as a leader or an outcast. In a WST-style 7C, this is depicted as choice and indecision, someone having to choose among a multitude of options: will he choose what is best for him, or for his community? Will he follow his delusions, or will he reflect on the various choices in front of him until revelation occurs? In the Mary-El's depiction, it is a lone wolf. Wolves are pack animals, they have a community — yet this is an individual. He has been separated from his pack, though we are not sure if he is a leader or an outcaste. His head is bowed, and there is a moon (reflection, intuition, the subconscious, illumination) in the background — all adding to the idea that he is in contemplation, he is thinking about the options before him. I get the feeling he has not yet left the pack completely, that he is on the verge of that emotional decision, and weighing the choices. Do you see how they are not really so dissimilar? And this similarity is arrived at through deconstruction — "minimalizing" — to suit and number.
You don't need to learn a whole new set of meanings when you understand the scaffolding. Then again, you don't need meanings at all if the images are clear — you can read the story the images provide and glean an incredible amount of value from that without ever learning a single meaning. Knowing the root, the minimal, the structure, does however help
Minimalist decks (whether modern or as old as the Marseilles and earlier) are pointing you to that root, rather than the superfluous crutch of representation.
I have both. I use both. I value both. I love seeing how different artists draw different shades of each card froward... but for me at least, I like to see thee thread that connects them all — and when you see that thread, no deck is really that different from another, provided is follows the tarot's structure.

Nobody is saying any of these decks like the Thoth are "wrong". The OP labeled the Wild Unknown and some other decks as "minimal" decks in the original post and that is what this discussion is about. In truth, the most boring/annoying interactions I tend to have on this site are with deck makers that drop by to push product and can't accept honest feedback from people that buy and use these products or be humble about it. I wish you well with your deck.
