Why is it that it seems like Gnome seems to be implementing Windows bad practices? The last thing Linux needs is a Windows registry. One of the greatest benefits of Linux IMO is the ability to configure applications in config files... not having to use some custom tool to manage the configuration.
At least it's got a fairly well defined schema unlike the Windows registry which is really just a very big dumping ground with a completely unenforced schema. You can just browse it and the settings are all there, complete with value type, default value and sometimes even a description. And it's reactive too usually, so you change the setting and it applies immediately to running apps.
Tbh I'll take that over KDE's million config files spread out everywhere that are mostly undocumented and trashes your formatting and comments everytime it updates the file.
It's actually a pretty good implementation of a registry overall.
Beginners won't agree with you. Imagine their reaction after hearing that they have to edit a config file written in an obscure script language they never heard of
