I think now there must be some kind of adapter code, even if auto-generated, that is a facade from v1 to v2. You can essentially use that to release a new v1 minor revision that depends on v2 for its implementation. But yeah the whole thing sounds sus, not easily applicable to other languages (where does this adapter code come from and how does it coexist with v2?), and like a bad practice even when it can work. You should really just migrate everyone to the new version instead of patching together something to handle stubborn users of the old version.
