Continuing work started in #3656, apparently that one got closed due to the author's account getting deleted

Am I right, that we execute on a pure default setup every available linter per filetype match in a row?

Should we add a check to stop after the first successful execution and on top of that should we add a priority for more than one available linter in the default list/map?

No – it is useful to get diagnostics from multiple linters. Especially in Python the linters address different things, for example mypy only checks types, flake8 is (mostly) focused on code formatting, and pylint does some semantic analysis as well. ruff attempts to combine most of the above in one tool, but mypy still does much more thorough job at type checking.

Ok, then I'm fine with it.
The doc wars tricky to compare against the initialization list due to the different order, but seems to fit. Thanks for updating it.
