I agree with both of you, and I'm suggesting ISO-8859-1 fallback
_only_ for compatibility with currently existing headers which already
contain ISO-8859-1, and for Reason-Phrase.  Sorry for being unclear
about that.

That's because I'd expect HTTP receiver implementations to do that
anyway, if ISO-8859-1 is seen in the wild, whether the specification
recommends it or not.

If it turns out that nobody, in real life, is using ISO-8859-1 at the
moment for those things, then of course drop it.
