No, that's not the point I was making (apparently I'm not very good at clarifying).   What I mean is that MTI means that an implementation of what is specified will be able to use the thing that's MTI when it's called for.   So it can't be #ifdef'd out and still be an implementation of the specification.   The mere fact that the code is there and could be compiled in does not mean the implementation conforms to the specification.   It has to actually be compiled in and operable.

As a general practice, ifdeffing out code that you've written tends not to be the right thing, because then it doesn't get tested and maintained.   c.f. "technical debt."
