Question about the future plans/maintenance of angularFire

Let me open with that I've enjoyed working with firebase, Angular and AngularFire over the last years very much.
And, that I'm very grateful for the effort and love that has been put in the angularFire library.

However, considering the open issue https://github.com/angular/angularfire/issues/3406 , which makes that angularFire is forcing us to remain on firebase-js-sdk 9.22.2; which puts us 5 months behind on releases.
Considering the fact that there have been no significant updates to the library nor the documentation; it would be nice to get an update on the plans related to AngularFire.

It seems that the library authors have not had the time/possibility/desire to work on AngularFire and that nobody in the community has been stepping up to fill that void.
Sad how that may be, because we love the library, it would be nice to know what the plans are (if any) going forward.

Of course it would be great if we get to hear that in the foreseeable future somebody will (be able to) invest time in the library.
However a "Sadly no, we are not sure/cannot promise that effort will be put in the library in the (foreseeable) future" would also be better than what we have now.
Because at least then we would know where we stand and we would know we have to plan the investment of moving away from the library.

Best regards

Start by reading issue #3406 and this issue's comment thread. Determine whether AngularFire has a documented maintenance plan; done means a clear, current statement of its future support and Firebase JS SDK compatibility.
