I've always thought that psql is pretty inconsistent, arbitrary, and
unreasonable about what it chooses to write to stdout vs stderr.
However, if we rejigger what goes where, we will surely break a lot of
users' shell scripts, since those already expect particular output to go
to one or the other. (We'd also break all the regression tests, but
at least those are within our power to fix.)
On the whole I'd vote against changing it --- a small improvement in
consistency is not worth the pain it will cause.
