Agreed that they are working on a lot right now, but not sure that whinge is warranted here.
It's a good thing that Moodlerooms are releasing all this stuff that they've been working on for some time and they are going about it exactly the right way, so I thank them 100%. I've been more aware of all that stuff for quite some time so it's less surprise to me.
The decision on whether and when anything gets into core or not ultimately lies with Moodle HQ, if we have a backlog then we have a backlog (and we have a backlog already).
