It seems to me that the most useful purpose for this registry is to
identify names that are resolved using the normal DNS protocol (not
like .local or .onion) but that are treated specially by some
application(s) above the DNS stack. So the 8145 key tag would go in,
as would evertything in _attrleaf, the latter likely by reference.

As to whether it's best or worst practice, I'd stay away from that and
just clarify that the bar for adding new entries is high because of
the risk that they will collide with existing non-special use.

R's,
John
