In reply to Rene.

I agree. Currently, tagging system in the plugins repository is a mess and a more strict categorization would definitely help.

Besides that, I don't know if it's just me, but I find the whole "tagging" idea a bit outdated in general - something that belongs to the "blogging period" of WordPress, with not much use nowadays (in most cases, categories is a much better way of organizing content). In fact, I disable tags in all my sites because sometimes editors find it confusing.
