I'd like to see the distinction between NaN and NULL retained, since the
two "values" arise from different circumstances and under different
conditions. If a particular app needs them to be equivalent, then that
is easy enough to do with SQL or triggers.

On a modestly related note, I'm come over to the notion that the
date/time value 'current' could be ripped out eventually. Tom, isn't
that the only case for those types which bolluxes up caching of
date/time types?
