Again, I don't agree. I think it should be configured.

Our infrastructure has configured it, just like everyone else can.

If you're forbidden from enabling mod_deflate, it's probably for a
good reason (CPU, support)

Smartly considering your content expiration is wise, having the
default conf guess is unwise.

I know what the headers do, I disagree that httpd should send them
with arbitrary values by default.

That should help people make smart decisions, but these are not
exactly obscure topics.

No clue here about starting with a "default build configuration file"
-- maybe you're starting with "httpd.spec". When you ask for deflate
or expires and build from source, they end up loaded in the generated
config.
