Uh, either your memory is poor or you need to review the mailing list
archives again.

The number of times people have asked "can I change [a particular
setting] without requiring a nsd restart" and have been given the answer
"no, config changes require a server restart" has indirectly suggested
that if we can move something out of the config and into the runtime
environment, it would be preferred as people ask for it repeatedly over
time.

Being able to tweak and tune thread pools at runtime has come up many,
many times.  Each time, the answer is: change the config setting and
restart, which usually wasn't desirable because restarts during the day
on a production system weren't something folks could do ad-hoc, as they
were running a single server, not load-balanced ...

Seriously, this has been a long-standing ask, to make more config
settings modifiable at runtime.  Perhaps the way compression has been
implemented wasn't perfect, but it was a start, and I think Jeff's
suggestion of shipping a filter proc that enables compression
server-wide by default is the right answer.  Making the setting purely
config-driven is just perpetuating the "sorry, config settings need
restarts" problem.
