And that is exactly the collective wisdom of the CREEK!
Having said that, I daily discover that I do not have enough "equipment at my disposal", but my wife disagrees!
On the subject, I have the magswitch featherboard that I use on my TS and router extension, as well as a second Veritas router table. Works great, but I wouldn't use it on a jointer.
I use my mag units for edge jointing when I'm edge jointing a tall/wide board. It assists on the bottom edge ensuring it remains tight against the fence while I focus on the top remaining perpendicular and applying the appropriate pressure.
I do have a 12" jointer and could see some value in face jointing applications, but I've an aluminum fence so no dice in my shop Also, depending on the workpiece, I will often skew the board as it's going through the jointer to reduce possible tearout (maple especially).

lots of guys use a power feeder on a jointer.
Seems to me that part of what a feather board does is incorporated the power feed.
I can't see it harming you but I'm unsure why I'd want to.
I have used the rigid version of these:

I used a couple of them like Mike mentions, just to keep the bottom edge tight on the fence for some edge jointing. As others have mentioned no real benefit to face jointing.
