You can't query, for example, which package installed some file, without
reading the complete +CONTENTS for all installed packages.
With, say, SQL database, you could do that under 10 blockreads.

Not much we can do about that, we usually follow the rule
one vendor distfile = one port
and it has served us well. I would be strongly against merging X.org
ports back into a monolitic port again.

bsd.openssl.mk does get included every time USE_OPENSSL is specified in
a port, but that's not a problem. The problem is execution of !=
assignments you pointed out, and these happen only when openssl port is
