I do not think we should be changing -N behavior. We should be fixing
--foreground. Whether you accept that fix into v3.5 is up to you IMO:
There are certainly reasonable arguments for and against that
acceptance. If you do not accept it, I think Squid v3.5 should log some
kind of "this feature is broken" warning when the option is used.

My recommendation is to accept v3.5 fix iff it is small and low-risk.

If we remove -N, there will be no way to disable SMP without changing
squid.conf. That fact does not necessarily mean that -N should stay, but
we should keep it in mind. It may be a good idea to replace -N with
something like --config-extra "workers=0" which would introduce a
powerful general replacement for the removed feature.
