No, it only reduces the runtime memory footprint.

Has never been a focus in the Squid development.

Yes, by using an axe and trimming away components or details you don't
need. But it's not easy.

debug symbols is deleted by the strip command, just as is done on any
other binary.

the other is to disable as many features as possible in configure. You
can disable all authentication, only build the dummy "null" storage etc.
This will cut down a bit.

The statistics is mainly if you also need to reduce the memory usage
while Squid is running. The first step there is to take away the
archived statistics (CountHist in, only keeping the current
counters. Then more analysis of the memory usage is needed to determine
which may be the next target to ax away..

In code I guess you could kill the client_db, ipc, neighbor relations,
swapout, StoreMeta* and a bunch of unneeded ACLs without too much
effort. Should also be quite easy to chop away everything related to
authentication. Then it gets a little tricker.
