The design point for eqn was secretaries who had to type mathematics
without knowing any mathematics.  Eqn does have usability bugs: if you
type (foo sub 2) it makes the ) part of the subscript, and you have to
use braces or say (foo sub 2 ).  But K  C observed that although mathematicians
liked the system (but did complain about the output), it was a complete
success with secretaries.

Nowadays, of course, we are all our own secretaries (and telephone operators,
too, but that's a different tale).

TeX is Turing-complete.  I could imagine a version of eqn that looked for
$$$ ... $$$ brackets and generated TeX, though.
