* `INP` flake8-no-pep420 - The pep 420 is something that part of us may
remember as the reason why napari stop working at some moment because of
some problematic files in `site-packages`.

 * `PYI` flake8-pyi - better type annotation
* `Q`, flake8-quotes - enforce quoting, but the rule Q000 is disabled
(see #5589).
* `RSE` # flake8-raise - simplify raise code by remove `()` when
obsolete.
* `RET` # flake8-return - simplify code readability by forcing proper
return schema.
 * `TID` # flake8-tidy-imports - replacement for absolutify imports
* `TRY` # tryceratops - enforce rules on exception raises like keeping
in try only this that could raise exception (see why it could create
problems in #5577).
* `ICN` # flake8-import-conventions - enforce import convention for
alias (like `import numpy as np`)
 * `RUF`# ruff specific rules -

feature works
- [ ] If I included new strings, I have used `trans.` to make them
localizable.
