Is anyone doing the Sitter to Sitter or Sitter to Sitter Plus programs?

I got an email asking if I'd like to take part in these programs.

Sitter to Sitter is if a pet owner in your area needs a new sitter to care for their dog during an ongoing stay, Rover will send you a message from their Rover account. They'll let you know why the dog needs a new sitter and you'll get the opportunity to accept or decline the booking. If you and the owner accept and you complete the booking, you’ll be awarded $50 on top of your normal rate.

Sitter to Sitter Plus is for sitters comfortable taking on dogs showing signs of anxiety or aggression. If you & the owner both accept you'll get an extra $100 per booking.

I guess this is pretty new & wondering if anyone has any good or bad experiences.
