My point was that having something built into the system is very different than having a dependency stricken free for all that is outside of the system. For this reason, especially for the majority of Window's life, it was not just "another option", it was a "hey, this is built in" option.

As your link show, Windows has homogeneity, with good config options built into the frameworks. In those frameworks, those built in config options can't be consider just "another option". There's no real homogeneity in *nix, so the only options is misc files to put misc paths.
