While I think it's obvious that Python 3.8 can be removed here, I wonder if it's still useful to mention all the other minor Python versions in each pyproject file. What do you think?

The root pyproject.toml file does not mention any Python version:

ITKElastix/pyproject.toml

Line 36 in d3ca819

"Programming Language :: Python",

Is that also OK?

The Python Packaging User Guide suggests that those classifiers are only informative, so I guess it may not be necessary to mention each minor Python version number:

Although the list of classifiers is often used to declare what Python versions a project supports, this information is only used for searching and browsing projects on PyPI, not for installing projects. To actually restrict what Python versions a project can be installed on, use the requires-python argument.

The minor versions are a signal to folks browsing the project on PyPI what versions of Python the project has been tested with.

I think we benefit from explicitly communicating the versions we support :-)

@N-Dekker thanks!
