For me, it gets harder and harder to keep track of the actual changes taking place in a particular ticket since there are a lot of cross-dependencies and no positively reviewed tickets have been merged lately, meaning the changes swiftly accumulate.
It might be helpful to state the ticket number in the commits which would make it easier to track the differences down, at least for me.
Or perhaps there is a nice git feature I am not aware of?
git log --first-parent
goes a long way

I think it would be nice to have something like powerset
and topology
that dynamically keep track of whether a (open) subset is contained in it.
This might also be a good opportunity to shift all this open_covers
and subsets
business to those classes and decouple it more from the manifold code. We can consider doing a similar thing for atlases, too. I can imagine that these changes could make pickling of manifolds easier.
This comes handy especially for sheaves, since it would allow to see them as (lazy) families indexed by topology
.
Opinions?
In principle, this could also lead to the more general notion of topological spaces. Manifolds are then nothing but topological spaces equipped with an atlas (roughly).
But to get there eventually, we need a lot of refactoring, i.e. something for the further future.
This is also good for subset topologies in case of e.g. embedded manifolds.
See also #31785 "Category of open subsets of a topological space".
