My feeling is that search lists for DNS are a bad optimization that
should never have happened.  After publication of RFC 1535, they
should have been removed altogether, instead of being half-patched.
    ftp://ftp.rfc-editor.org/in-notes/rfc1535.txt

I routinely dot-terminate domain names and disable search lists,
and I believe software should treat any given domain name as it is
presented, without trying to second-guess the intent.  Software should
not try to guess intent when the syntax is unambiguous.

It is way too late to catch this particular horse, but removing bad
optimizations from current software releases would still be a useful
step to take.  It would certainly be better than continuing to keep
them around due to some notion that inertia is invincible.
