Should we switch to EffVer?

[rcap107]

At Euroscipy 2025 I followed a talk about EffVer, and I was wondering if we should make a more conscious effort to use this kind of versioning.

The gist of it is making it more evident when there are bigger changes, and more practically this means that we should not remove features in patches (like we have done in some cases), and instead do that only in minors.

This would also mean having more frequent minor releases, which I don't think is a big problem.

I was thinking of this when I opened #1566, because I think that changing the requirements and deprecating a bunch of stuff warrants a minor release.
