I am going to answer my own question. Got a hold of a yn 622c tx, put it on my panasonic camera, couldnt fire a flash. So it doesn't work.
Um.
I have the Panasonic G3 and GX7. I have Canon YN-622 gear: YN-622C (MkI) transceivers, a YN-685, and a YN-622C-TX. It all
works just fine for manual/remote power control; obviously no TTL/HSS. The fit in the hotshoe is tight, but I didn't have to force anything to get it to seat properly in the Panasonic hotshoe; but this is where I've read of varying experiences. I've also read that using the Nikon versions or sanding/shaving some of the plate can make it fit better, but I'd prefer not to go there.
My YN-622 combos also work the same way (fires correctly; remote manual power control) on my Fuji X100T.
So. While it didn't work for you; it does work for me.
Best option, though, is probably to wait for the MFT Godox X1 stuff to arrive.
