I don't think it's correct to remove it like this. Technically it existed in the P2P protocol, so at least the number should be kept as reserved.

we can always repurpose it in the future. Reserving it says to me that it still WsServer or active.

I do not agree, either we should implement it or w should remove it, having somthing in the core that is not implemented (and is not documented) is not a good practice, might exist in the past by mistake, but should be fixed, there is no hardfork for this, should not bother.

I have to say that there are too many things in the neo core that is not documented, not commented, not explained, not in proposal, the only way we learn it is by reading the code, but this wss is even a trap of implementation, it exists, but not work, as chris said "Reserving it says to me that it still WsServer or active.". only very few of us know how they works, this is by no means a good practice.
