Unfortunately, there is not much difference between hidden dials and not - the same memory is still consumed, for instance.  Except maybe for the sparsity of the dial parameter interface - but even then, with dial groups, an apparent sparsity can be accomplished by group organization alone.  So the real effort is in restricting control - that is, subsuming control to the default interface provided.

I'm not convinced there is a purpose beyond this (control).  One can 'hide' infrequently used dials in an infrequently accessed dial group for so-called 'experts' without resorting to draconian measures (file hacking).

C makes it easy to shoot yourself in the foot. C++ makes it harder, but when you do, you blow your whole leg off.
