Meh, there's things like array comparison functions that require both
arguments to be the same kind of arrays. And array_agg that requires
the elements to be the same type as the state array (ie, same type as
the first element). Not sure there are any taking just one specific
type though.

Are we still waiting on these two items? Egor, do you think you'll
have a chance to work it for this month?
