Now that Godot 4.1 is out, it would be great to see the signal name conflicts resolved as well as the other ongoing Godot 4 issues like mesh culling and 3D support.

GDExtension also has a backwards compatibility system in place now and no breaking changes are expected in the future. Perhaps the implementation could be ported to GDExtension?

midiphony-panda Spine has some custom import code (to create SkeletonDataAssets, Materials, etc...) and it's maybe not recommended or tested with Unity's parallel importing ?

Thanks for asking. Regarding the spine-unity import logic it is safe to enable parallel importing.

In case anyone should ever encounter issues with parallel importing (even though we have not yet encountered any issues ourselves in tests, nor heard of any), please do let us know, we're happy to fix them.
