Uhm, no.  This is kinda like delete every line that isn't executed.
Sure you can do that, and even after doing that the compiler would run
the testsuite and pass with flying colors, the problem is when 100% or
95% of all real code stops working.

Instead, put in a warning that says 'tell Martin you're using this bit
of functionality, or risk loosing it in the next major release.' run
it that way for a while (year), then remove them.  Put a unique number
in each, so that you can tell quickly which reports go with which
code.
