I think raiding, as a game-mechanic, is mainly useful for tribals and nomads, who really need it as a source of extra income. It's a strong counterpoint to the gold poverty of these two forms.
However, does it actually have any purpose as a religious/culture ability? The important raider countries (Scandinavians and hordes) are tribal and nomad anyway, so they can still raid, but the shift to feudal/iqta/republic becomes a more meaningful transition from raiding for money to farming for money. Currently, the raiding ability for eg. a Norse raider is lost after their culture shifts away to a non-raider type after they reform/convert their religion, become feudal, but since culture shifting/splitting is much less interactive and unintuitive than reforming the religion or establishing feudalism, it makes little sense to me.
The main victim of this change would be feudal realms picking up paganism or Paulicianism for the raiding, but I think it's a strategy that ought to be weakened. Hindus, too, if they still have the ability to raid in CK2+ (I don't know because I always play with India off).
