Well, ED has been a little silent of late here. He said he's been busy, so you might need to hold onto the idea for a bit before he gets back to you.
But, from my reading of the base Researcher class feature, it seems to be a two-part effect.
1) You choose two Researcher Fields of Study. From now on, you have access to features from those field, if you qualify for them.
2) You instantly gain a Feature from one of the Researcher Fields you have chosen, for which you qualify.
So, yes, I'd say that counts as a bonus Feature. Besides, if it was just the first effect, that Feature wouldn't offer any bonus right away, only promises of more in the future, and I think the designers of the game wanted all Features to be usable and fun immediately. ED might rule differently, as is his right, but I'd think most people would agree that you've got a rare bonus Feature for it.
