Comment (by reneeotten):

 I am working on this update and will put up a PR once I've finished up a
 few remaining things. NumPy v2.0.1 supports PY39, the latest upstream
 version v2.1.0 supports PY310 and above.

 I would propose the following:
 1. keep the current version as {{{py-numpy-legacy}}}, this has to conflict
 with the latest versions as Python packages cannot be installed side-by-
 side.
 2. list all dependents and:
 - remove all subports below {{{39}}} where possible, if needed going down
 the dependency chain
 - if a port depends on Python < 3.9 and is deemed to be valuable and
 cannot be removed, then it should depend on {{{pyXY-numpy-legacy}}}
 - update all ports if a newer upstream version is available, or if not,
 rebuild the port with NumPy v2.0 and enable/run the test-suite to verify
 that it still works correctly. If no issues are reported by using {{{ruff
 check path/to/code/ --select NPY201}}} I think we assume that things are
 likely to work.

 I *think* this is the only way it can work, but am open to
 comments/suggestions.

 I will update here with a link to the PR once that is all fixed and we can
 start adding ports/updates there and once we are fairly convinced most of
 the things will work, then we can merge. Additionally, once that's the
 case people who are interested in older systems should verify that this
 all still works and if not provide patches to make that happen if
 possible. The build system has changed to {{{meson}}} and upstream is
 using a vendored version with NumPy specific changes. Our {{{meson}}} port
 has quite a few changes specifically intended to support older OSes, but
 integrating these modified {{{meson}}} versions sounds complicated and not
 something I am willing to invest time in.
