There are may ways to be "better".  The claim is that using narrowing
instead of (nth 1 prog-indentation-context) will make mmm support
applicable in more circumstances because it reduces the amount of
changes needed in each major mode (in many cases the required changes
are reduced to nothing).

I don't think anybody claims that prog-indentation-context makes it
hard/impossible to get as good mmm-support as what Dmitry
is suggesting.

They are just 2 alternative (and mostly equivalent) ways to get the
same result.  One of the two requires changes to every major mode and
is currently only used by antlr+python.  The other is used by
mhtml-mode, mmm-mode and generally requires few if any changes to
major modes.  Also changing antlr+python to use the other approach is
easy and leads to marginally simpler code.
