An uninstaller would still be cool so you could delete all the skins, textures, meshes, sound files, etc., when you were done with the mod. You're right about enabling mods in the Morrowind menu. You'd still have to do that. I'd just like an easier way to clean out all the crap when I'm done.
And in my defense, the page does say the following:
You will HAVE to use latest WinACE (2.x) or WinRAR (3.x)
or PowerArchiver or FREE ZipGenius to be able to uncompress the mod files.
Nothing about Winzip there. Maybe winzip *will* unzip the file but are there meshes or other resources contained in it that require those other less-common archiving tools? Who knows? The page doesn't say. It's pretty emphatic about what you HAVE to have though. 1 A/\/\ N() 733Y d00d with a hardrive full of warez that I need to have winRAR on my PC.
