Sure, an individual function like this has almost no negative impact.
On the other hand, working around its absence is also trivial.  You
can create a wrapper function that does exactly this in a couple of
lines of SQL.  In my opinion, saying that people should do that in
they need it has some advantages over shipping it to everyone.  If you
don't have it and you want it, you can easily get it.  But what if you
have it and you don't want it, for example because what you really
want is a minimal postgres installation?

You can't take anything in
core back out again, or at least not easily.  Everything about core is
expanding very randomly - code size, shared memory footprint, all of
it.  If you think that has no downside for users, I respectfully
disagree.
