Many clarinets have these, and it seems that the ultra highend ones do. However, I am also aware that these are sometimes used to repair a cracked tenon.
Without having cracks, are there any advantages to having tenon rings? Disadvantages?

Actually, it's more common to see tenon rings on intermediate-level clarinets (wood only) than on high-end models. They exist to protect the tenon end fro chipping, denting and general wear when assembling the joints. Pros are careful when assembling their clarinets so don't need the rings. Student instruments nowadays are plastic so don't really need the rings either. Come to think of it, nobody needs them.....but some people (myself included) like the way the look. I don't believe they have any effect on how the clarinet plays. They may have some beneficial effect on reducing the probability of cracks starting in the tenon itself.

From my 3 Bb clarinets, my R13 doesn't have them, my R13 Prestige has them, and my Eaton International doesn't have them but it has laquer on the end. Does that tell you anything? Only you know.

This '82 B&H 1010 I've got has metal tenon rings on all tenons (like all the lower ranking wooden B&H clarinets), but most other 1010s I've seen haven't.
The older Selmer's top tenon ring is of an unusual design as far as clarinets go as it not only covers the outside and top of the tenon, but also lines the top few millimetres of the bore as well.
Though they really could have done with putting one on the bottom joint tenon as the wood is pretty thin there.
And if these tenon rings are loose, it will seem like there's a leak on that particular joint as air will leak between the tenon ring and the wood, so when replacing the tenon corks on tipped tenons, run some ultra-thin superglue from the cork recess side into the tenon ring to make sure it's well sealed, and won't give you a false reading when testing for airtightness.
I think it's either the old Cabart or Thibouville-Lamy clarinets which had lined sockets as well. The full Boehm Selmers had the middle socket lined, but Leblanc full Boehms don't, and the anchored pillar screw holes went through to the inside of the socket.
