The registration information in section 4 looks good and has the appropriate status,
so I believe this to be OK for registration by IANA.

As for HTTP considerations, I expect Link-Template to be potentially useful as
a trailer as well, particularly to supply optional links determined by the sender
while content is being generated (i.e., after the header section has been sent).
However, the spec doesn't even mention trailers. This would be a good time
for Mark to review what we wrote in 

   https://www.rfc-editor.org/rfc/rfc9110.html#considerations.for.new.fields

and be sure that the spec documents those aspects not already covered by the
choice of structured syntax. [Use of Link in trailers wasn't mentioned in RFC8288.]

Cheers,
