Make a limit on how many people can be @ed at once

I feel like this feature would be useful, although I do have @mentions @here and All roles turned off. Some people decided it would be a good idea to type individual users in manually in a mass message and the only way I could combat this was to remove there role which disables them from talking in my discord with the way I have it setup.

I was at work when this happened. I dont think I am the only person that could benefit from limiting how many people someone can @ at once. If possible it would be nice to adjust this per role in the text chat section or who knows maybe have a cool down option after so many users get @'ed at one time. Either way I think this could be a useful tool as I know many discord servers are not setup to require a role in order to talk so some may not have it as easy as I do to temporarily combat this issue.
