The software model was fantastic. 9.0 broke it a bit with some toolchain changes, but those were easy to fix.
We've been keeping it up to date to. We even were super happy when arm64 windows started working and we could use it. We've got a whole suite of plugins built around the old model.
I'm not surprised we're probably the biggest remaining user of it. And also not surprised that gradle never improved the new plugins. TBH I wouldn't be surprised if those get killed in 11.
