Under Steam Deck Compatibility section-
some games are in status "Unknown" (or even "Unsupported")

I would really love to "subscribe" / get notified if a game I like moves to status "Verified" or even to status "Playable", so I can buy it safely.

it would really help me to manage / track and follow my wishlisted games.
I really love playing on my Steam Deck, and I don't want to miss out any good game
