LGTM

Sorry for the delay - I try not to spend too much time looking at code on weekends.

You should be on the lookout for any breakage that happens as a result of this.

Maybe also turn the docs build on for pull requests? I just checked and I don't think this break the docs build but it could have.

As of now I didn't find any, meson nicely exposed the subproject's includes so they also don't need any change and workflows are also green.

Right the current docs should be fine as it is very bare-minimum (all relying on autodoc extension)
I am working on a doc branch to add more content, there I'll also add the docs build on PR

@SwayamInSync This still looks good to me, I'd be happy with you merging it

[SwayamInSync]

Waiting for the #246 get resolved first as this restructuring might cause confusion there :)

[SwayamInSync]

will do the rest updates, within new repo

LGTM, feel free to merge once CI is green

[ngoldbaum]

Merging! Maybe ping in the #user-dtypes channel when you're ready for someone to create the new repo?

[SwayamInSync]

Yes, I'll reply on the sebastian thread, about creating repo.
And we can start the shifting process, it'll be good to do the release from new repo as that might automatically update the info on pypi and later conda (which I assume requires manual fixes because a lot is changed from last release)
