That's about recategorising articles that have been put in the redirected category, and yes if that became a big problem it would be worth resolving. But if you have category redirects and you use hotcat to add categories it will automatically add the category that you are being redirected to, not the category that you typed.
I love HotCat and cat-a-lot, but only a fraction of users use them and we can't expect all tools to work like that, they're broken enough with the current categorization system (think of the Upload Wizard).
And if people do add the redirected category I believe there is a bot that will move it to the target category
Conversely if you were searching for a particular category in Tamil, if there were a category redirect it would take you to the corresponding English category and tell you that your search word redirects there.
All that currently works,
I don't think the search works like that at all.
http://commons.wikimedia.org/wiki/Commons:Category_redirects_suck would seem to be a dormant draft that discourages people from creating category redirects. But it may be time to reopen the debate and make this an opportunity to make Commons more multilingual.
How about a policy of "Our category names are in English, but you are welcome to create category redirects from other languages".
The category system seems to be hard enough to understand without redirects. That's why redirects are disabled on category namespace pages. Besides, you didn't address my comment that it would be a localisation nightmare. Really.
