FWIW, this doesn't solve the problem of /unintentionally/ revealing
sensitive information, such as the name of an information source, e.g.,
when that corresponds to a file name.  I think, information distributed
along with a file should be obviously visible, e.g., when looking at a
file with a decent viewer or it should only be written intentionally,
such as, e.g., XMP data.  Data relevant for the work-flow shouldn't be
archived, by default, since it may be sensitive information.

Those users who know about PTEX.FileName have far better chances to get
TeX do what they want - set \pdfptexfilename to 1 - than those who don't
know - and needed to set \pdfptexfilename to 0.

I did not get much support for my proposal, so I think I should be
satisfied with a new primitive.  No need to discuss this further.
Honestly, thanks for your work on pdfTeX!
