If the requisite switch is provided and it can be added to a site
configuration file, does it really matter one way or the other?
The answer is "No" for experts who know of the existence of the switch
and are fully able to tweak their setups. But as Stephan pointed out,
for casual users the answer is likely "Yes". For they won't know
of the switch, or they won't feel comfortable tweaking their setup.
Therefore I think many pdftex users would side with Stephan and Peter.
As for myself, I will accept whatever pdftex's developers are prepared
I do, however, have the following question.
Why does PTEX use:
/PTEX.InfoDict <object ref>
/InfoDict <object ref>
I would have thought the dictionary approach more in keeping with PDF's
design, and it would certainly provide a cleaner path forward when adding
new pieces of information to support custom post-processors and the like.
Therefore I'm wondering was the dictionary approach specifically precluded
by Adobe when Hans registered PTEX? Certainly AR is not phased by the
contents of a /PTEX dictionary, provided it is syntactically correct.
