Let's continue to use them as we prepare for 2.6.0 - where we have the
opportunity to drop ABI and pack all of our bit flags in one place, that
still makes a lot of sense.  So would adding a group of bitfields, as was
the case in one of the commits I noted.  An int (for alignment) and three
int-bitflags still saves us two ints in the structure.
