Because you just complained about them not releasing updates? Work on the underlying distribution is most likely going to be slow for a while longer since they’re continuing to work on Cosmic. I’m sure you have your reasons for doing it this way, but you’re already using a different DE than Pop comes with. Why not put your DE of choice on another distribution where you can get the normal system updates you want?
I originally responded to you with a suggestion that I hoped would be helpful, not knowing what your experience level or reason for using the distro was. You responded by being rude and insulting. I hope you have a good day!
