Why doesn't Dolphin come with each game's ini files already set up?

[Landfill7377]

I have been going through the games in my library and adding all the necessary game specific settings based on what the wiki says. But I'm wondering if all this information is documented on the wiki, why doesn't Dolphin come with each game pre configured with these settings in the default config files? I noticed certain settings will be there in the default config, but not all of them. Also, why not include the widescreen AR and gecko codes that are on the wiki for each game? If there is a reason for not including all this, could there at least be an option to download the latest game configs and widescreen codes in Dolphin?
