When you look at how long it’s been around versus where Xf86/x.org were on a similar timeline… yeah, we’re almost halfway through the life of the project, if history repeats itself. Its replacement may be expected to start designating it “legacy” and its boosters sneering at out-of-touch Wayland users well inside a decade.

(It fares better compared against x11 instead, but not as much-better as one might guess—either way, it’s been a sloooow moving project)
