IMHO, we have to base our decision on this issue with what web servers
actually emit these days. I meant to collect the stat on C-D header fields
 a long time ago, but haven't managed to do that.

That's why I had resisted RFC 5987 for rather long while, but 'Chrome' 'gave
in' and implemented it. :-)

Before rushing to remove it (as an optional 'fallback') , I'd like to have
some 'numbers' about what web servers do (FYI, some Google products emit RFC
2047 for Firefox and Chrome at the moment, but I guess Google has to switch
over to RFC 5987 for Firefox and Chrome). I'm not sure whether the cost of
supporting it is larger than the benefit.
