It is absolutely not reasonable.
It completely goes against the entire goal of what FPP and RFP seek to achieve.
They’re selectively altering the profile of each depending on website based solely on @celenity’s arbitrary judgement.
If their goal is to minimize breakage they should solely use FPP.
If their goal is maximum resistance they should solely use RFP.
Doing something in between like they are is a very wrong approach to the compatibility issue.
As others like @sha123 have said for months: no it does not.
