This isn't just Gentoo mentality, it is an old, well-known programming
pitfall that is all too easy to fall into.  (Yes, I know, systems
administration isn't programming, but the same principle applies.)  Here
is some wisdom from fortune(6) on the matter:

Premature optimization is the root of all evil.

The First Rule of Program Optimization:
        Don't do it.

The Second Rule of Program Optimization (for experts only!):
        Don't do it yet.
