Adding scheme interfaces without using them?

[Lukas-Fabian Moser]

Folks,

is it acceptable to submit a MR that adds a scheme interface to some C++ 
routine without using that new interface in LilyPond proper?

In my case, I made Bezier::solve_point Scheme-visible for some work 
project of mine that is too spezialized to submit as a MR (at least for 
the time being). But without the addition of ly:bezier-solve-point in 
Scheme, I can only ever engrave my work project with a custom-compiled 
LilyPond differing from Master.
