unnecessary-dict-comprehension-for-iterable (RUF025) now exists as a flake8-comprehensions rule (adamchainz/flake8-comprehensions#553).

Although C420 has not been implemented yet, it would make sense (and seems to match what has been done before) to merge the rules in favour of the flake8 plugin. Although the rule request was made to Ruff first (#9592, adamchainz/flake8-comprehensions#552), my understanding is that Ruff favours strong coupling to flake8.
