Rogue Operatives = Beta keys

It's fine, it's actually a ReleaseStateOverride key which is commonly given to users when the game is not actually released (usually developers will generate this type of keys before the release and give them out to early access players and testers), and as long as the key sub contains the same depots as the release (store) key, the game will function exactly the same as what you bought from store.

Beta Testing keys don't work like what you said. If the key indeed gets revoked, then you should update to the correct giveaway feedback.

I have a key got from other group recently. I guess this key can work properly as a normal key. It is just a description of the key while the developer tried to get it.
The game was released half a month.

It does not mean it will get removed from your library later.
I get a lot of press keys and most of them are "for beta testing".
Nothing to worry about, they stay in your library.
@PlyrStar93 does a great job explaining for what you do need to look out for.

it might be a full key, depends on each title.
