I remember using save/restore extensively,
back in the early 1990s.  However, back
then I had one PostScript Level 1 printer
to support, and so needed to write Level 1
code.  Level 1 printers had limited memory,
so there was an incentive to husband it.

I also used save/restore to restore a
convenient graphics state.  These can take
some trouble to set up, and it can be
useful to easily restore back to it.

Never used setglobal as that is Level 2.
