Whonix documentation onion <- overkill?

I understand having an onion for the forum but this seems a bit much for a read-only service. It also would be prohibitive for many people. I can imagine many people trying to read through pages of whonix documentation over a slow node or 2, growing tired of waiting minutes for text and giving up.

Could someone please let me know if there is any practical purpose for this?
