I was told this was beneficial (but optional with modern trannies) for two reasons, 1) rev-matching for smoother clutch engagement but more importantly 2) Speeding up the layshaft for reduced wear on the synchros when aggressively down-shifting.
I had an older Nissan and they were known for using cheapie brass synchros that wore out quickly.
Does the SynchroRev feature of the Z also speed up the layshaft on downshifts?

I don't believe it does, at least from what I understand of it. Double-clutching will still have the same benefits and drawbacks on the 370Z as it does any other modern car (smoother engagement in corners, but more clutch wear per shift). I never did see anything that definitively lead me to believe double-clutching reduces synchro wear on modern cars though.
With SRM enabled, double-clutching will be even easier than it is on other cars.
