Pylint, ESLint and Clippy all let you enable or disable lints via human-friendly names e.g. Pylint lets you configure:

disable= wildcard-import,
 method-hidden,
 too-many-lines

The idea is to also support such human-friendly names for ruff in pyproject.toml, while still somehow supporting the numeric codes for backwards compatibility. The reasoning being that symbolic names are much more human-friendly than cryptic numeric codes. Case in point projects that care about readable configs end up adding comments to every numeric code in their config: zulip, fastapi, sphinx

Currently Ruff requires every rule to have a numeric code, which I don't think makes much sense given that Ruff also has Ruff-specific rules ... and I don't think we should have to introduce new cryptic numeric codes when we introduce a new Ruff-specific rule. This obviously requires quite some changes to the codebase/UI but I think doing this is worth it.

In particular I would like us to follow the Rust naming convention for lints:

the lint name should make sense when read as "allow lint-name" or "allow lint-name items"

I think this is a very nice convention because it results in descriptive names. And currently many of our lint names are not descriptive, e.g. TrueFalseComparison should probably rather be called EqualityComperatorForTrueOrFalse, UnnecessaryMap should probably rather be called MapWithLambdaInsteadOfComprehension.
