Yes. Simplifiers parsers consiredably if they don't need to know the
parameter token to tell if it's value is allowed to be quoted or not.

Not entirely sure what you refer to.

RFC2047 is very strict on when it may be applied.

The 2616 BNF very often uses constructs where 2047 can not be applied,
either from the BNF only allowing ASCII (not TEXT) or from being outside
the scope where RFC2047 may be applied.
