In my opinion, _adding_ non-standard features to standard programs is
what should be justified, not keeping them out. (This applies doubly
for ill-thought-out features.)
There is not much use for this "feature" to begin with, since 'sleep'
by its very definition cannot be used for high-precision sleeps. It
waits _at least_ as long as the specified time; the only guarantee
that it makes is that it doesn't sleep for less than the specified
time. Because of the way it is an had traditionally been implemented,
a better operational bound than that is impossible. Because of its
definition, it can't be used for high-precision sleeps anyway!
Because it has little value except that NetBSD can now claim this
great new feature, and because it encourages people to write
non-portable scripts, I definitely think this change shouldn't have
