US-ASCII is also what MIME has always specified, even before HTTP
was specified to use its variant of MIME.  Being an intersection is
convenient; but it's also been the standard.

The IETF recommented no more (or less) than compatibility with the
existing standards.  I'd expect any standards body to do that, even
one with the substantial international participation of the IETF!
