Ok, but isn't this something you do for new functions, not ones that have been in use for years?
Isn't there research on the use cases from when you first introduced this function? What has changed in the intervening years? Have people recently stopped wanting to interpolate several sets of data at the same points at once?
This reminds me of the ode solvers which have a handy syntax where you can supply extra arguments which are also then passed to your solution function and event and output functions, but it is deprecated and not documented because TMW have decided users are too stupid to understand the feature.
