Re: bloatware like Wayland
Sure, X11 carries lots of baggage – show me Wayland after 35+ years and then we can compare.
Also, one reason why it is smaller (beside X11 containig lots of stuff quite irrelevant nowadays) is that pretty much everything X11 does is against the Wayland philosophy – forwarding, making screenshots, programs positioning their own windows, … Yes, I am aware that many of these things can actualy work in Wayland. The developers are not completely Poettering-level insane. Fortunately. But anyway…
X11/Xorg has shown its strength by integrating lots of things no one even dreamed of in the 80s. Sometimes seamlessly, sometimes less. I am looking forward to its 40 year anniversary.
