Is it safe to self-report exited validators?

Hello! In general, self-reporting a validator adds a label to that validator which indicates that it belongs to some entity. That in itself doesn't affect the self-reported validator's RAVER.

If you’re asking whether it will affect the entity's aggregated RAVER (since a new validator has been added to its historical fleet), then if the validator is still live (unexited), then it would affect the entity’s RAVER moving forward after being self-reported. If the validator has already exited, it won’t affect it moving forward. We have previously done a backward refresh/recalc, but would be custom work.
