Does MLIR have any kind of policy on bumping versions for Python dependencies? The LLVM project is generally very conservative about dependency requirements -- you can easily build LLVM against LTS distro packages. However, the MLIR nanobind requirement in particular is being bumped *extremely* aggressively -- the version required here is so new that it's not even part of the *upcoming* Fedora 43 release (a leading edge distro).
