Jack - no, max power it is. The confusion arises over the term 'TOGA'. On the 737 there are buttons which select TOGA power. It is that this TOGA press does other things involving flight directors and the like and the manufacturer's recommendation is a manual setting of max power ('straight arm'), PNF adjusts as necessary, while PF wrestles with the machine, flying basic pitch attitudes. The flight directors will not give useful information for a stall recovery. Once that is complete, the F/D can be reprogrammed to your heart's content. On a 'standard' g/a, pressing the buttons is fine as the F/Ds will give the right commands. Max power applied at a lowlevel stall will, as you should see above, while recovering you from the stall, make the a/c a handful and will also produce a huge nose-up pitch.

Bobcat - it is fine as it is. I think having it 'give up' the moment you touch the levers would be a mistake. It would only have taken a momentary press of a button to get manual control. We also get quite a lot of 'sticky' throttle movement due to friction where the throttles do not respond finely to the A/T demands and such a function might interpret this as pilot 'interference'.
