for the same reason we don't have pdfplain.tex and so on: maintenance of
the result.

in the unlikely event that don corrects a bug in plain, each
conglomerate plain package would have to be updated.  with the existing
setup, the correction happens automatically (ctan and packaging updates
happen [almost] automatically).

note that we *have* had a plain correction since pdftex hit the streets,
so the hypothesis isn't entirely fanciful.
