TASK: Return multiple nodes instead of using NodesToAddCollector

[sabbelasichon]

Relates: #3982

[sabbelasichon]

@simonschaufi We should either remove some complex rarely used rules which uses the NodesToAddCollector or refactor them. This can be quite cumbersome but we should move forward.

@sabbelasichon The title of the issue doesn't make it clear that it also removes some rules. Why did you actually remove them?

[sabbelasichon]

Too old. Never used them. Never seen them in the wild tbh. Drop complexity. Let us focus on important things

[simonschaufi]

ok but then we should also mark the commits somehow because we also don't really follow semver at the moment.

[sabbelasichon]

I don't really care. Being pragmatic in that regard
