Why doesn't Debian have a GUI to upgrade versions?

Me and a friend of mine that migrated to Linux are wondering this since we both updated to Trixie and had to ask chatgpt or look up online for console commands, to later accept changelogs and stuff we don't quite know the implications in the update process. We're both kind of tech-savy so we could sort it out but it doesn't look like too much of a hussle to make a graphical interface to automate/guide the process. It would allow Debian and Linux to get more users in the long run.
