I might throw in a bit of gossip here - many who were following the development of GD 4 last year (myself included as I was using it :) ) thought it was kind of rushed out in time for GDC 2023 in March. And immediately after GDC, Godot 4.1 followed (and now rc's for 4.2), with lots of fixes.

So on the one hand, yeah, 4.0 lacks polish, and I certainly have felt some strong feelings working with GDExtension... but I also believe there was a reason for that, and I believe the team when they say they're working on improvements now
