Keeping ABI compatibility by itself is not an hack - the current
workaround is an hack, but that's only because the current way of
doing things in code generator is a bit ugly, and I did not want to
spend too much time on it. It is purely an implementation issue, the
fundamental idea is straightforward.
If you want a cleaner solution, I can work on it. I think the hour or
so that it would take is worth it compared to breaking many people's

I think ABI issues are mostly orthogonal to versioning - generally,
versions are related to API changes (API changes is what should drive
ABI changes, at least for projects like numpy).
I would prefer passing to "numpy 2.0" when we really need to break ABI
and API - at that point, I think we should also think hard about
changing our structures and all to make them more robust to those
changes (using pimp-like strategies in particular).
