This "Factory" feature should not be managed at the pdftex level, only supported eventually.
In my mind, this is more an option for wrapper tools like texexec or latexmk and all the TeX frontends.
However, the name "Factory" can at least be suggested as a reasonable value of --output-directory in the pdftex man page.
Maybe we can go just a small step further with an optional parameter
pdftex --factory foo.tex
that would be equivalent to
pdftex --output-directory=Factory foo.tex
A wrapper tool like latexmk would support the "Factory" design as follows:
the command "latexmk --factory foo.tex"
would call "pdftex --output-directory=Factory foo.tex"
for backwards compatibility with older pdftex versions
A more clever behavior for pdftex is perfectly possible but is by no means desirable (at least IMO).
For example, latexmk could guess that "Factory" should be used even if no --factory option was given,
by first testing whether some Factory/foo.* file exists.
This "clever" behaviour can be overriden by the --output-directory="." option.
I don't know if many people would use this --factory from the command line,
but the fact that it exists would suggest both users, teachers and frontend developers that
it might be good practice to use it or support it.
