Could you please provide a reproducible recipe?

No.  You have good forecasting abilities ;-)

`TeX-arg-ref' is overtaken by RefTeX, if present (or, to be more
precise, when `reftex-plug-into-AUCTeX' is non nil), so I miss the
point of your suggestion.  `TeX-arg-ref' is just a convenient function
that can be used in AUCTeX for both situations: RefTeX present or not.
In general, in AUCTeX we don't deal directly with RefTeX functions.

Bye,
