The branch here on the ticket merges the above tickets and makes violations an error again.

Tools:

• Find them with ./sage -tox -e relint - but the list of .all modules that it complains about differs from what actually became a namespace package in Remove __init__.py files for subpackages designated to be namespace packages #33011; this is updated in Remove imports from sage.all and sage.rings.all in sage.rings #34189. (See also tox -e relint: Do not complain about imports from sage.categories.all #33202)

• import_statements: Accept more flexible input #34426

• Refactoring tool to fix modularization anti-patterns #34945

Other tools (not used):

• https://github.com/asottile/reorder_python_imports with option --replace-import ... but it rewrites all imports in a peculiar style (one import line for each imported name)

• https://pypi.org/project/import-linter/ - this could replace our use of relint for complaining about .all imports
