I also see the move to the GUI very critically. First off, I dont 't like all that clicky stuff, it is usually inefficient compared to editing files. Second, my feeling is that I loose control. It is not about backups only, it is about getting a fast overview, how things work, and how things break. Without this maintaining my Home Assistant config can get a nightmare, as all the stuff is abstracted to some shiny stuff. I had problems with integrations before (Luftdaten) , could not fix it, so I dropped it and made an own template sensor… Not the best experience so far.
