No, you are correct.  My meaning was more about intent; in the early
days of the change to INVOKE I’ve seen a couple of warnings telling me
that a phase returned #<unspecified> or #F, but that didn’t result in
aborting the build.  We have decided a long time ago that the only way
to exit a build should be through an exception, so I think it’s time to
update the last few build system remnants of the Boolean assumption (on
core-updates).
