Will legendary effects be disabled in unrated BGs?

I was pretty sure the answer to this was yes, but I wanted to directly ask if things like

would be disabled in unrated random battlegrounds?

Is it correct to assume :

In Legion, as soon as you zone into a PvP instance, the stats on your gear will be nullified, and you'll be given a pre-determined set of stats that's uniquely configured for your specialization. Furthermore, any set bonuses, enchants, Legendary bonuses, or trinket effects will be deactivated (although your Artifact and its related Artifact Powers will remain active).

means ALL pvp in any form besides world pvp?
