It doesn't supersede ambient per se, but supersedes one particular ad hoc usage
of ambient, which was to cause objects to glow.

The rule of thumb for POV-Ray 3.7 is that if your object glows in the dark, use
emission.  If it doesn't, use ambient.

I would say no, because then you'd have everything glowing when radiosity is
used.  This was already a problem with the stock textures in POV-Ray 3.6
(especially with the metals), though not everyone may have noticed it.
