If you want, you can collect such mappings in a separate module.
I could not make your code working - does it require a later LuaTex
version (than 0.80.0)?
Here is a complete working example (OT: The location of the limit is still
ugly with xits fonts)
\setupbodyfont[xits,10pt]
\appendtoks
\catcode`∫=\activecatcode
\letcharcode `∫ \int
\to \everymathematics
\setupmathematics[integral=nolimits]
Nolimits $\int_0^∞ f ω$, and $∫_0^∞ f ω$
\startformula
\int_0^∞ f ω,\quad ∫_0^∞ f ω
