Can you breaking change a PSR like this?

I don't think it's wise to do a complete reversal in a PSR like this would

Personally, I *just* refactored some small, unimportant projects to use the 
suffix.

In any way shape or form I sincerely hope you don't implement a "breaking 
change" to a PSR like this.
