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.
-- D.E. Knuth
The First Rule of Program Optimization:
Don't do it.
The Second Rule of Program Optimization (for experts only!):
Don't do it yet.
-- Michael Jackson
