actuall, the fact that the spoilers didn't deploy was spotted rather early on.
I would assume, but that's just a guess, that those 11 seconds were spent troubleshooting the system (wonder why they didn't spot the TL then...)
A "spoilers not deployed - manual override" might be far easier than the troubleshoot.
But of course those inhibitors serve the task to protect from potentially more disastrous outcomes if the prerequisites aren't met...
