You are not wrong. Email headers have some more requirements than
bodies, so that it was up to now not deemed reasonable to remove
the restriction to only use 7-bit octets. But maybe time is ripe
for at least a proposal to remove this restriction. News headers
are also moving in this direction. Ideally, and in accordance
with the newly formulated IETF charset policy, one shouldn't
go to use =?charset?R?XXXXXXXX?= (where "R" would stand for
raw), but should declare that (within "cooperating subnets"),
UTF-8 is directly used. Using anything else in headers without
being labeled (as it is unfortunately done is some areas) greatly
affects generality, interoperability and future extensibility.
