TextMate doesn't necessarily have to modify its own Info.plist, right? By constructing a helper app, e.g. in Application Support, with a tailored Info.plist based on info collected from the active bundles, and then using lsregister to register/unregister UTI types there wouldn't be any need to even run it (example below, based on http://apple.stackexchange.com/a/175395). 

/Per


with:

 ~$ alias lsregister=/System/Library/Frameworks/CoreServices.framework/Frameworks/LaunchServices.framework/Support/lsregister

register:

 ~$ lsregister /Applications/UTImportCalvin.app
 ~$ lsregister -dump | grep -A 4 CalvinScript
		description:   CalvinScript
		flags:         imported  active  apple-internal  untrusted  
		icon:          
		conforms to:   public.script, public.source-code
		tags:          .calvin

unregister:

 ~$ lsregister -u /Applications/UTImportCalvin.app
 ~$ lsregister -dump | grep -A 4 CalvinScript
 (empty output)

where UTImportCalvin.app's Info.plist contains:

...
	<key>UTImportedTypeDeclarations</key>
	<array>
		<dict>
			<key>UTTypeConformsTo</key>
			<array>
				<string>public.script</string>
