Can't say I've noticed, but then again I haven't been looking. I would be curious to know what a coach would do with me that I haven't been doing with stuff like trainerroad. It must be an interesting time to try to be a coach, there's a wealth of apps and information that anyone can get most of the way there on their own. Personally, I would like to get into helping non-cyclists get started with cycling training and helping them find their way to using bikes as a way to get in great shape (even if they have no intention of racing).
Every thread in the Road forum has a 98.1% failure rate in providing sound advice to other cyclists.
Don't look in the training and nutrition forum lol
