The most relevant issue is not about non-PostScript output, but
about using PostScript features that cannot be accessed in PDF.
Yes, there are many examples of this; e.g. all of the PStricks package,
and many of the advanced features of Xy-pic.
There are various programming techniques;
e.g. pdfTricks and LaTeX2HTML
that require use of a dvi --> ps --> "other format"
sequence in the overall processing.
Yes, the pdfTeX binary could be used with \pdfoutput = 0
to obtain this; but I doubt that this would get around the package
compatibility issues that the original poster claimed he has faced.
If such compatibility issues are causing a problem then it is these
that should be faced and fixed. Removing support of one binary
is not an adequate solution, in my view; it's likely to create
a different set of problems without really fixing the ones that
prompted the action.
All the best,
