The fact that we have a scarily large surface area for that to
cause problems is not a great argument for making the surface
area even larger. Also, I don't think v13 has been out long
enough for us to have full confidence that the backtrace behavior
doesn't cause any problems already.

If there's an elog call inside a critical section, that seems
like a problem already. Are you sure that there are any such?
