Sould fifteen round championship fights make a return?

[ICB]

I think it would be more interesting if like in the case of a draw like
Marquez /Pac if the ref goes to each corner and asks both sides if they want to go the fifteen.

Well something did happen like that before but not quite like that, Tony Thorton went 12 rounds with Doug DeWitt. And they drawed then they were ordered to go 13 rounds to break the draw.
