I think this would be an excellent discussion.  Summarize away.

As for compatibility, there are (of course) things you can do
in Level II that you can't do in Level I, but there's nothing
in Level I that you can't do in Level II.  Most of the new stuff
can be emulated on an old interpreter, but you can't implement
something like "undef" very easily in Level I PostScript :-)
