Hi Euler,
As you may have already read, separating the max_replication_slots parameter
is also discussed in the following thread.

I agree with separating the parameters.
I think we need to discuss the names of the parameter.
Parameter names were also discussed in the above thread.
It was suggested to name them 'max_replication_origin_states' or
'max_tracked_replication_origins'.
Personally, I find 'max_replication_origin_states' easier to understand,
although it is a long name.
