Now granted, once we can reliably do incremental build, the question

presumable incremental build only try to compile stuff that _need_ to

incremental build the ccache hit should be 0%
Not quite, I think. Consider a header file changed within
in #if-skipped region in a way which does not change the
number of skipped lines. I expect this would trigger a
recompile and that ccache, other things being equal, would
find a hit on the cache. Does this sound plausible.
Still, I would expect the hit rate to go really close to 0.
