This concerns schez-scheme-for-racket, not the current chez-scheme for
which we are packaging the bootfiles, am I right?  Given that we build
a set of bootfiles that would be enough to go forward, we no longer
need the original bootfiles beyond that point, i.e. the "bootstrap
bootfiles" would only be needed inside chez-bootstrap, but not chez
itself (which can instead use the native-input).  Am I missing
something here?
