One difference I see is that there are millions of hardware with no force touch, already in market. And they will still be around for years to come. Developers will not hide stuff behind force touch, but just use it as a convenient method to access common tasks, preview stuff etc. I think this convention will stick around. It will just improve user experience for those who use it and will not make a difference for those who dont. Kind of like pro user features.
