Doesn't mean they shouldn't train to, but its moot to compare onself to a pro in that regard.
Where is the issue in taking on board that you might not be an amazing climber on ascents over 30 min in length, but if you have a killer 20-25 minute power why not work on pushing that? Without
compromising your health if you're finding it hard to drop below a certain weight?
We have a local kid who is exactly that. He's the business; two seasons in Belgiu, heading back again next year and even had some chats with Alan Pieper. But found there was a limit to his weight loss, below a certain point he could never avoid getting sick and power would drop.
Now works on his 20 min power and is an absolute beast.
It's not all black and white.
