This sounds reasonable to me. Starbucks is everywhere. But when you do have options they're far from the top choice.
You could have a look around to see if you have any local coffee roasters and then find out who they supply to try and get something a lot fresher.
I think enforcing some universal API for this would be a decent compromise. This would allow browsers to handle the UI which means the user can set a global preference or set it per site. At the very least the UI would be uniform so you wouldn't have to fight dark patterns trying to disable them.
