glibc and a few other critical packages depend on Python using python-any-r1. python-utils-r1 has _python_run_check_deps() which checks PYTHON_PKG_DEP w/ has_version. We set PYTHON_PKG_DEP to a bunch of tight, recent versions which is enforced via BDEPEND. We then verify that at build time. This is problematic in two cases at least: 1. Portage will try to aggressively upgrade glibc and Python may not have been upgraded first (despite its BDEPEND, but whatever) 2. Sometimes an out of date system may find it hard to upgrade everything and piecewise updating a core lirbary or two is desirable, but this won't work if the right Python slots are available but not the right recent versions. I think we should just check for the correct Python interpreter slot + use dep in _python_run_check_deps, or maintain a list of alternative baseline versions for checking in _python_run_check_deps instead. (We could also, for python-any-r1, iterate over the tight ones, then iterate over the loose ones, to reduce the chance of picking a weak one unless we really have to, but I don't think it's worth it.)

Lower bounds are cumbersome to maintain and cause problems when upgrading outdated systems, particularly when sys-libs/glibc is involved. We could technically apply some hack to make any-r1 dependency checks to conditionally ignore minimal versions but that sounds like unnecessary complexity. In the end, minimum versions were primarily enforced to make sure users got the latest bugfixes but that doesn't seem strictly necessary.
