Dconf is amazing. Lots of tweaks in a centralised place, searchable, with naming that makes sense, and documentation. It’s standardised and it’s legible.
It’s not like the windows registry, in which stuff just gets dumped and isn’t standardised at all.
Config files can be a mess. They’re strewn around your system everywhere, aren’t always named in a way that even lets you know they’re a config file, you have to hunt them down individually, and syntax differs between them.
Saying it’s like the windows registry seems kinda true from a surface level, but all the things that are actually wrong with the Windows registry aren’t present in dconf.
Similar systems exist on other DEs, and this isn’t a new thing, it’s been around for a couple of decades.
