Restricting Ranked play based on FPS

So I was playing Dark Souls 3 recently, and when I was adjusting my settings, I was booted to the main menu when my FPS got "too inconsistent for online play." Which made me think: would it be a good idea to restrict who can play ranked based on whether or not their PC can get a consistent frame rate?

Now, if this was implemented it should only be for ranked, cause that's the only time t outcome of the game really matters. And, it shouldn't matter what the consistent frame rate is, just as long as it's consistent.

Is this a good idea? Honestly, I don't know, but it's worth giving some thought, I think.
