I think few users know that they can actually request the gadgets extension likely because Help:Extensions doesn't list it. Although it  works the way you explained it.

There is a thread at dev.wiki somewhere about someone who designed a similar javascript tool, although it shares the same drawbacks as this blog notes. A simpler alternative is to store the configuration files as plain text in the Mediawiki namespace, and extract the content using Javascript. As long as the script cleans it up safely, constant Javascript reviews shouldn't be needed.

A better alternative is to try and get Gadgets 2.0 finished, which has this and many more user friendly tools for beginners.
