This is bought to you by the people that think /etc/sudoers is best replaced with javascript rules and the solution to a mash up of javascript and compiled languages not freeing memory is to ignore the issue for 7 or 8 years then admit that the issue is unfixable and solve it by manually running the gc constantly and noting that this performs in practice way better than you would imagine for such a hacky crappy solution.

In practice most users not using fedora are "apt" to see wayland not sooner than they upgrade to ubuntu 24.04 LTS or Debian 11 or later and as users will naturally upgrade when they feel like it as opposed to release day one would expect the majority to transition between 2024 and 2028.

Apps which don't work on X before this period would be even more niche than usual.
