There's no contradiction. pdfTeX is an engine that understands DEK's
TeX typesetting language, but it's not the same as his "tex" program.
And no matter what is closer to your heart, tex-live (and tetex) don't
use DEK's tex program except for plain tex, they use pdftex.

According to the file itself
the following primitves are undefined:
$ grep undefined pdftex-dvi.tex
% we make the undefined primitives available as \normalPRIMITIVE, so
So there are many more. On the contrary, the microtypographic
extensions are still defined:
% these public primitives remain usable in dvi mode:
The problem is that microtype tests for pdftexversion and pdftexrevision
and adjusts its code according to what it finds. I think that this
approach is just exactly what these primitives are meant for. It should
be possible to use them for that purpose, and not do strange hacks.
