I think these old functions where obsoleted a long time ago; but the
byte-compiler warnings and describe-function help machinery to show
them as obsolete is much more recent. So yeah, probably there wasn't a
byte-compiler warning on 21.1 saying `unfocus-frame' was obsolete; but
the function *was* obsolete anyway and suitable replacements had been
introduced (and, I  presume, documented).
