Ghostscript seems to be no problem at all.  It is very permissive.  Of 
course, if one continues to run an outdated version of Ghostscript it 
might go so far back that it could not understand %%BeginFeature, but 
then, a backup version of config.ps would provide %%BeginPaperSize.  At 
some time, the 3.0 Structuring Conventions have to take precedence, just 
as LaTeX2e is elbowing out the old LaTeX. The real problem is the !PS 
2.0 vs PS 3.0 header, because there is more to PS 3.0 than the format of 
Structuring Comments.

The alternative would be a conditional in config.ps.  Is that possible?
