There's a New Features board that this could have gone under. You aren't the first to mention this and I would link you to a great past discussion, but I can't find it.

Category behavior would have to change to make what you suggest possible. Currently categories are treated as a tag on an article, instead of articles being listed on a category page. If Admin could simply rename the category page now, no pages that were in the old category would be transferred to the new thus you have a new category page but also a broken one. This is why categories do not have a move option as it would cause only problems.

However, there is a script, CategoryRenameAuto-update, that allows you to rename the page and then automatically update all pages. Since this script makes many edits, it's suggested you get a bot flag on the account that uses it.
