I have seen packages before which do not use -O2, probably due to bugs
in the compiler.
Now, bugs are hopefully transient, but they do exist.  Actually, I
think some packages had problems like this on the alpha architecture,
for example.

I agree with you that -O2 is ubiquitous; this is why most packages use
it on their own, obviating the need to specify it in mk.conf to begin
with.
