Sure, but I already covered a better design. Remix can be expanded to have ALSO an alternative version that is more Classic-like; the game engine is almost the same nowadays anyway; it's not like they really use the old game engines so it's really not "truly classic" technologically (so it's mainly a matter of gameplay choice when they design).

No reason to overcomplicate it. Remix can just be expanded to have an alternative version (in addition to current Remix) that is more "Classic like". It's not that different technologically under the hood; the game engine of current Classic is not the original client anymore anyway; for the most part it's a gameplay choice at design and not a requirement.

Yeah but that's a another topic (so it's effectively a strawman). I do not suggest to only have 1 Remix; I said to have 2 Remixes; 1 of them would be more "Classic like". I didn't even change a stance on later replies (which would be still legitimate (people are allowed to change opinion)) because on the original post I said "Remixes"(plural) and not Remix (but sure I expanded on that more clearly on the later replies in the topic (on having additional alternative Remixes)).
edit: PS I added a clarification on the original post, that covers that very clearly, because it's not your responsibility I wasn't clearer on it.

Easy to have a 2nd Remix that does that. "This Remix-2 character can not enter the future world" the end done. Technologically it's not a huge deal either but gameplay-design-wise it's as easy as that.
