I will bet the full dollar that Trinity never gets ported to Wayland.
They would have to port it to a version of Qt that supports Wayland. If they were ever going to do that, they would have done it by now.
MATE (GNOME2) ported from GTK2 to GTK3 so most of MATE works on Wayland today. You can use all the bits with a different Wayland compositor. And I think they are making their own.
But Trinity maintains their own fork of Qt3. Bringing that up to Qt6 or adding Wayland to Qt3 would be a big project. I do not see either happening.
And quite a dishonest readme at that. All the “not natively supported” entries for things designed to work with XDG desktop portals are hilarious.
This is obviously more of a political statement than anything else. I would not expect much from it.
