Weird DSC comments from Adobe apps

Some of the Adobe applications on Windows XP (from the "creative suite")
produce their own PostScript instead of relying on the Windows GDI 
(what is a good thing in principle).
When printing to a printer, they use the printer driver's write through
capability but behave strangely:

(1) the DSC comments in the write through snippets are much the same
    as if the app directly writes a PostScript file bypassing the
    printer driver stuff.
(2) the snippets are bracketed with comments on a per page basis:
    %ADO_BeginApplicationHeaderComments 
    at the begin of the snippet,and
    %ADO_EndApplicationTrailerComments
    at the end of the snippet.

In between there are the usual comments like %%BeginSetup, %%EndSetup,
%%Page: x y, and even %%EOF.
As the pstops filter does not know of these weird comments, it gets
disturbed by the DSC comments of the included snippets, especially the
%%EOF comments act as a premature EOF condition, so nothing comes out of
the
printer.

Are there any plans to work around this issue, or should I file a STR
on this?

PS: The latest DSC spec by Adobe mentions these comments as a
preliminary
stuff that is going to be removed in the near future, but this spec is 
now nearly 10 years old.
