Huh. That is very surprising to me, but I stand very corrected.

I would consider it to be pretty bad practice to treat query params this way, extra query params should be ignored. However, web standards are descriptive, not prescriptive. If enough sites have strict requirements about the number of query params, then it doesn't really matter what good practice is, and Facebook should accommodate this by moving back to cookies or at least make it opt-in or something.
