It's starting to look like one of those accidents where a number of opportunities existed to "fix the immediate problem":
1. If the TOGA function is inhibited due to A/C being on ground then get an automated voice to call out "MANUAL THRUST REQUIRED" or some other warning.
2. Or "Don't inhibit TOGA operation if nose wheel isn't on the ground" (or would that be more dangerous if hit accidentally at the wrong time?)
3. Pilots change SOP to shadow thrust levers
Probably a few more minor variations as well.
