My concerns do relate to my '17 Mazda6, yes. OEM spec'd fluid - is simply 75W-80 GL-4. They do not say any more than that.
Having said this, Mazda does offer the following:

I cannot seem to find out whether this is a semi-or a full-synthetic. The rear of the bottle does say synthetic.
Nowhere can I seem to find out what the kinematic viscosity is at 100C and 40C.
As to whether I would impact waranty... well, I would think it would be hard to prove that the wrong lube is in there. Not saying I would do this, but it would be easy enough to drop out the old lube and put in new OEM approved lube. Also, I am somewhat of the mind that warranties are held out to be better or more important than they really are. If something screwed up in my transaxle big time, I am not that sure I would let anyone muck with it. I have a workshop manual, I would get a Harbor Freight 20T press (with arbor plates), and I would get the necessary bearing splitters and would work with a machinist to make up the necessary tubular press fixtures. I guess I am at a place in life where I have alternative vehicles, and I would do the repair myself.
I do agree that I need about 10,000 miles on the transaxle to really pronounce the synchro's duds... I am, as time goes on, learning the idiosyncrasies of the 'box... and learning how to make it work for me. Slightly delaying the shift action, NOT double-clutching, increasingly works. When I really want to go, I either do accurately double-clutch, revving it to 3500 in first, or sometimes, I with mimimal clutch-slipping, start in second. Part of the trouble, here, also is that first gear is so, so granny-geared... Any rednecks on your tail threaten to bang into you as you shift so early-on, due to gearing.
Thank you for your interest in responding.
