This touches on something that bugs me about all the commercial editors using TextMate-compatible bundles for language support: It's not clear who, if anyone, is maintaining the bundle for a specific language.

I doubt the developer of editor XYZ commits to actively maintaining the 2 dozen language bundles they distribute with their editor. So support for language X might forever be that Last-updated-4-years-ago zip file that perhaps wasn't even the definitive version when it was found, especially for the less community-orientated languages.

but if someone writes a better textmate bundle, all the editors can now use it! it's not like vim and emacs support all the languages themselves either.
