Good idea but it doesn’t work in dom0 
I would like to thank you all very much for your help! Especially @otter2 for this PR: Exclude GNOME from usability & ux documentation by RandyTheOtter · Pull Request #1744 · QubesOS/qubes-doc · GitHub and the code in Quick Quality-of-life Improvements.
So here’s the current state of my scripts:
Git repo: parulin/qarulin-outgoing: a reverse ~/QubesIncoming directory - Codeberg.org
The docs: qarulin-outgoing: a reverse ~/QubesIncoming directory — qarulin-outgoing documentation
I tried to leave some docs for anyone willing to achieve the same result without my low-quality code. There is still a lot of improvement that could be done.
