It means the steam client has finally trashed its legacy 32bits code and has finally a native wayland backend (keep Xwayland for old games). Ofc, it would have a wayland->x11 fallback (force-able with a command line opition), like with a vulkan->GL->GPU (force-able with a command line option). It means too I finally have to code my wayland compositor (full dma-buf/vulkan/CPU), probably based on valve one (but in C and/or assembly, not that abomination of c++).
