ну шо, новый булен на подходе
https://developer.blender.org/T67744Status as of Aug 17, 2020: The implementation is complete. There is a known performance problem, which will be fixed soon, and other opportunities for performance improvement still. Most bugs found by initial testers have been fix, though one is still outstanding. This code seems in reasonable shape (to me) to include in 2.91. But still need a review and agreement from the rest of the Modeling Module before this is certain.
