I agree. I'm saying we already have the notion that a client is blocked with a pending command, that can get re-executed once the blocking is done. (That is how the normal command blocking works). The blocking mechanic is functionally the same as the other wait (wait for a replack from k replicas then unblock).

Consolidate various BLOCKED_WAIT* states (#562)
f927565 
There are currently three block types: BLOCKED_WAIT, BLOCKED_WAITAOF,
and BLOCKED_WAIT_PREREPL, used to block clients executing `WAIT`,
`WAITAOF`, and `CLUSTER SETSLOT`, respectively. They share the same
workflow: the client is blocked until replication to the expected number
of replicas completes. However, they provide different responses
depending on the commands involved. Using distinct block types leads to
code duplication and reduced readability. This PR consolidates the three
types into a single WAIT type, differentiating them using the pending
command to ensure the appropriate response is returned.


Fix #427
