Yep, we do.
Btw, you should list coaches who have ladies skaters still competitive internationally in the 20s post puberty.

There is literally 2 skaters 20 years old, and 2 skaters that are older than 20.
Out of 20 skaters.
That is (1).
Now, (2). Since when skating past 20 is a good thing?
I said it multiple times, and I say it again. While I will miss my favs, I would rather see them win everything early and retire at 18. If i had a kid and it skated at elite level, I would want my child to leave sport around 18.
Why? First, injuries. It is something that builds up, and becomes worse over time. Not only that, but it is something that won't truly heal. It is something that will return when the skater gets older. All those fractures, injuries and so on will return as pains and health issues when the skater is 40+. I want my favourite skaters to be healthy adults, and not be like Plushenko. I want them to leave sport while they are fairly young and things heal better, and before they accumulated too many injuries.
Second, life. I don't want my favourite skaters to have coaching as the only option. Not everybody is made to be a coach, and not all coaches are successful. Getting a good education in a different while skating at elite level is not trivial. Getting a good education when you are 25 or 30 is also not trivial - all your friends have jobs and families already, and you are the only one studying with no money and so on. It breaks my heart when I read how Bruno Massot struggles financially, or how Serafima Sakhanovich struggles finacially. Leaving elite sport early, after winning your share of medals and earning some $$$, with the option to earn some more in shows, to take any direction you want sounds like a great option to me. That is what I want for my favs.
I really see 0 reasons for long careers in ELITE sport to be a good thing.
