Discovery with links would need to be specified also.
E.g., what type of links are we looking for, etc.
So in any case, there would be a resource connecting to representations.

Content negotiation is simply an existing mechanism
for connecting a resource to representations,
so reusing it seems better than inventing a new link-based negotiation mechanism.

Furthermore, linking assumes that there is a finite number of representations,
and not a combinatorial explosion of all combinations that can be made.

Finally, it integrates with negotiation in order dimensions, such as
"give me the French document in XML conforming to profiles X, Y, Z".

> Why is automated discovery needed?

Because it's a manual thing otherwise.
You don't want your client to ask you what links to follow.

> Do you have a real need to require profile creators to register their profiles with IETF?

No such registration is needed, just like no registration of MIME types is needed.

Best,
