@soller It's such a hard subject really because it challenges the identity of what a DE upstream should be and how standards work on Linux.
My hot take is Gnome should provide technology to make a customised DE so more of a standardisation body than trying to make a tight opinionated product. The more it deviates from being a tech provider to being a product the more upstreams will do their own thing because the experience at distro level should be varied because the use case varies.
