Yes, and I can't think of a single reason why we'd let people specify
anything in millibytes, or kilobits. Truth is, I bet many (if not most)
DBAs barely know that case matters in the units. And even those that do
are likely to prefer ease of use to pedantics.

As for the comments about SI datatypes and MySQL-isms, there's a hell of
a big difference between muddying the line in a config file for ease of
use and stomping on data that's actually stored in the database.
