Really? I wouldn't see it this way. I wondered a bit about the
number of primitives shown in the document of Joaquín, but that they
are used certainly doesn't make context like plaintex.
I have calculated the number of primitives from the list made in "TeX
Reference Manual" by David Bausum (of which there is a web version at
https://www.tug.org/utilities/plain/cseq.html).
According to that text the number of primitives is exactly 326. In my
document I rounded it to "approximately 300".
That list is a bit old. In the meantime we got etex extensions, which
adds a few more, and then pdftex ades some, as well as omega and after
that of course luatex. In luametatex we dropped some, and added others,
so there we currently have 770 primitives. The increase of number is
partly due to the 166 extra math related primitives of which many deal
with all kind of font related paraneters and inter-blob spacing.

if yuou want to know if something is a primitive, say:
\meaningfull\vskip \par
\meaningfull\relax \par
\meaningfull\framed\par
and you get an idea (\meaningfull itself is a primitive, the more
verbose \meaning, and there's also \meaningless which I let you figure
out yourself; of course these add two primitives to the repertoire).
