Surely ">A" may invite "Hmm, is it important that A gets empty?", so
the choice between the two is not so black-and-white.  It just is
that "touch" has a more specific "update the timestamp while keeping
its contents intact" meaning, compared to ">A", which _could_ be
read as "make it empty and update its mtime" but most people would
not (i.e. "update its mtime" is a side effect for any modification).

Thanks.
