I agree here. But having a few of those dynamically configurable is a
good thing.
What happens when your server reaches the limit of MaxClients where that
limit
is not even close to the HARD_SERVER_LIMIT. Now you have to do a
gracefull
restart to change the situation. I have been told by many people
that during the high load when your server is close to its limits
like MaxClients, they do not want to do a restart.

With this you have the ability to change it without the restart..

There is not complexity involved. Instead of having that variable 
as currently used in the Apache server that variable is in shared 
memory. For the rest it is the same where on top of it modules
like SNMP and MOD_BACKHAND could benefit from it by doing more
adaptive management based on the load of the server.

May I read this as "if more poeple want it then it is OK"??
