How come COSMIC has a fully functional Wayland compositor in such a short period?

The road to Wayland has been slow and painful for GNOME and KDE and I've been there all along the way for the past 8 years, but in a matter of a couple years and in its current alpha state, the COSMIC compositor is pretty much on parity with these, screenshare works, VRR is implemented, fractional scaling also, copy and paste works 100% of the time and to this day I still have drag and drop issues on Plasma pretty much breaking at random, but on COSMIC, it's working fine. It took several years for the other two leading desktops to tackle these features. Isn't this an actual amazing feat worth more recognition?
