BorderlessMaximizedWindows can be set in ~/.config/kwinrc, but is not accessible from the graphical system settings interface. This makes it effectively undiscoverable unless explicitly and successfully googled for, and even then some users might feel uncomfortable editing config files. Since I repeatedly see people asking about it, it might be worth exposing this option in the system settings.
Seems reasonable. Options without a GUI to enable them often bit-rot. Wanna take a crack at it? Adding a config GUI in the System Settings page isn't that hard. I can help you, and we have some documentation here: - https://community.kde.org/Get_Involved/development - https://community.kde.org/Infrastructure/GitLab#Submitting_a_Merge_Request

Where should I post in case I have a question?
Cool! The #kwin Matrix room is a reasonable place to ask.
It was said by KWin developers that not exposing this setting via the GUI was deliberate because it makes it too easy to get stuck in an unwanted configuration, so closing this.
