That's great. She gets a chance to feel like what she wants is duly considered, but she also accepts limits. I teach a method of parenting and working with kids that involves negotiation called Collaborative Problem Solving. There is a website at Thinkkids.org that offers resources for learning this method. Kids want to do well, but may not have all of the skills they need. They need to feel heard and recognized, and they will follow a workable solution much better when they have a say in it than when adults just tell them how it is. Besides, it helps them to think it through and learn how to solve problems for themselves.
