If all apps abode to it it would be nice because you could just backup config and skip all the other stuff. <type>/app hierarchy is much better than <app>/type because that allows for example of easily excluding ~/.cache from backups.

... but of course some apps must be super special flowers that need their own dir

Yeah, I find it especially annoying when apps do use the XDG directories but use them incorrectly (dumping a bunch of state/data in .config is unfortunately too common). If apps want to do that I wish they would just grab $HOME/.appname rather than mess up my .config dir.
