Protocol fees are only collected as part of the deposited rewards coming from the VotiumStrategy contract. Votium and Convex rewards are claimed and deposited back in the protocol as an explicit compound action.
On the other hand, SafEth accrues value by the passive appreciation of the underlying LSD tokens backing the protocol. There is no explicit process for claiming or compounding this increase in SafEth token value. The protocol isnt collecting fees from this side of the split.
It is not clear if this is by design or a potential oversight in the implementation.
