Actually it is a massive improvement: expensive niche features are now optional, features you have to discover and handle dynamically. This helps to avoid developer/vendor lock-in by 'tons of features required'.

If I am not too mistaken there are several "remote desktop network protocols", maybe the dev teams behind them could agree on a common network protocol.

And the more compositor implementations, the merrier, a bit like the x11 window managers.

I am coding mine for linux and AMD GPUs, as a hobby, in RISC-V assembly running on x86_64 via an interpreter (thanks to wayland being an IPC interface)... well until very recently, it has been more some kind of research and development of a "method" to code modular assembly projects with a minimal SDK, in other words to decide on various technical compromises requiring coding _real life_ software in order to hit the right sweet spot.
