I'm not entirely sure why it would be cheaper and more efficient to keep
your object files in ccache rather than in the build tree. It takes time
for ccache to do the preprocessing and fetch them, and it takes even
more time to redo the linking.

Disk space is cheap too, and you can always 'make clean' or even remove
all the source files too, if you really care.

Not that I'm presuming to suggest that there's anything _wrong_ with
your choice of workflow, of course -- it just doesn't really make much
sense to me.

Branches just seem like a source of complexity and hence pain. Using git
was just starting to become sensible for newbies, and now when people
are forced to deal with multiple branches it's all horribly painful
again.
