Player account features

I’m looking to start making an online game for the company I work for, and I’m browsing around to see if GDevelop would be a good fit. What I’m really interested in right now is the player account features. I noticed in the wiki that it says “Player accounts is still experimental and new features will quickly be added,” and I’m wondering if anyone has any idea what “quickly” entails. It looks like maybe finding the “player unique identifier” has already been added, have any other features been added or is there a timeframe for when they will be? TIA!
