Because some (much rarer) changes need other generated files to be
removed as well.  So bootstrap-clean does the above, but it also does
other things, including forcing the rebuild of temacs, which is almost
never needed.  OTOH, if someone wants to test a fresh build, or build
a different configuration, or some other relatively rare jobs, they do
need to remove all those other artifacts.
