Wine has two forms of WoW64. Old WoW64 uses 32-bit libraries and has been around for a long time.
New WoW64 (first available in Wine 9.0 if built with a special option) works without 32-bit libraries, but is still incomplete. It cannot yet replace old WoW64 everywhere, and even where it can, it reduces performance in some APIs. (For example, OpenGL.)
It will eventually make sense to drop the old one, but doing so now would be premature.
