If you want to maintain backwards compatibility. I am still sitting on
the fence on that, but I currently lean to propose a clean cut and
producing a setup.ini file for backwards compatibility for some time in
parallel with some new file that uses the new syntax only.

That doesn't make any sense, since the requires would be the union of
all depends already. So, 2.880+ should ignore the requires: and use the
union of [curr] and any version specific depends:. But maybe I
misunderstood what you want to be doing.

Wait… I thought libsolve-based was 2.880+?
Again the note that the libsolve-based setup.ini format should include a
way to provides: a named feature that other packages can then depends:
