+A small pylint update lead into a full-blown dependency updates.
+
+That, additionally, lead to deprecating Python 3.8 and 3.9 support.
+_Technically_, as of writing this, https://devguide.python.org/versions/ does NOT show 3.9 as deprecated.
+However, many dependencies have already dropped support for them - and, according to the page, 3.9's deprecation date 2025-10.

+### Development details / information

+The project will _soon_ ™️ migrate to `uv` for anything related to packaging, testing, and building:
