That's a bit philosophical.  open-..-start is advertised as a high level
option, and CC Mode only binds it to nil at a low level, the "engine"
level.  Binding user options to set values at a low level is quite a
common practice in Elisp programming.

The actual bug here is that find_defun_start in syntax.c doesn't do any
cacheing, hence is scanning from BOB far too often.  How about we see
how things work once this is fixed.
