I would much prefer an open registry, since it is the best way to
avoid name conflicts and show what's out there. A registry doesn't
bless a particular entry, it just prevents accidental collision.
My header-format reference manual includes an open list:

I also have a mailing list for Internet mail implementors. To subscribe,
send an empty message to
imis-subscribe(_at_)list(_dot_)cr(_dot_)yp(_dot_)to(_dot_) Contributors can
focus on the needs of their users, without artificially separating IETF
fields from non-IETF fields, SMTP from NNTP, etc.
