One possible problem could be the continued take-off with uncommanded reverse on one engine scenario - pilot rudder input may lead to short brake application on one side .... would not want ground spoilers at that point! Perhaps one engine in TOGA input would override?

You definitely would not want this as a take-off function. But if we follow skallas' idea that the logic would only be effective when we have a Thrust Lock condition, which by definition requires the affected TL to be in the CLB detent, then the case should not occur during take-off, only during landing. That said, an inadvertent movement of a TL into the CLB detent during take-off could be one of those non-obvious failure cases that would dictate against the logic.
