And I am building dimmers, thus I need to turn the light on and off many
times per second and DMX is irrelevent (unless you can offer DMX dimmers
in the $5 to $10 per channel range when buying 4 channel blocks).

For the most part.  And their slow speed is why a 60hz A.C. dimmer
works.  But just because the output cannot reproduce the frequency, that
is no reason not to have the frequency.  E.g. CD audio was (and remains)
a useless waste a fidelity for most purchasers of CD content.
