Yeah, sorry, I misread your post. You're still incorrect, though: you'll notice that the FAQ you linked to specifies a store purchase, microtransaction or activation of a gift from another user. This excludes retail keys and free licences.
Retail keys (and fod-games before fix) do still give access to everything (afaik) but Steam Market. I have alt.account that I used CD-key to get those permissions, so it definately works.
