Whilst times change & rules change if a title is awarded for life (no matter whether USCF, FIDE or anyone else) reckon chess.com will be respecting the same pattern. Nothing will be rescinded that is silly idea.
USCF Titles and Chess.com

Do you think chess.com should honor categories?
4th and 3rd free gold, 2nd and 1st get free platinum, and everyone above gets diamond.
At least, that's what I think. I don't have a title myself.

Would you guys happen to know since when has the USCF been awarding titles?
Probably since it was established.
Hmmmmmmm. I guess AndyClifton is one too, then.
