that local wiki's MediaWiki namescape pages may make less overload of

from files.
I think, default messages are in PHP code files and these PHP codes may
be compiled and cached between apache is alive. In other hand, messages
saved in local Wiki are in DB, and they are got from DB server by all
page requests.
Messages are almost never retrieved from either the DB or from files.
They're normally retrieved from memcached, regardless of where they
originate. As far as I know, there should therefore be no difference
at all between whether the messages come from files or from BetaWiki.
It's good policy to blank messages that are the same as the default,
but only so that your wiki will get any updates or improvements to the
defaults automatically. (IIRC, a blank message is treated as
nonexistent, and it preserves the history publicly, so this is likely
preferable to deletion.)
