Tinhte.vn is a 15M board and is a top 5 site in VN. That's what they do and they rank extremely high because their tag pages are really managed well.
You are free to use however you like it on your site. I just want to share the idea behind this addon as I have been talking to the owner for a while.

See how well the tag page of tinhte.vn ranks. It shows as #4 for me. And they have just used it for few months.
Coming from VB 3.8, I know this issue really well but the idea is to make it useful for
your users. SEO benefits are just added benefit. I'm sure you have read that Google will penalize sites that are over-SEO so the lesson is to help your users find relevant contents, the rest will take care of themselves.
