Not very practical.
Probably just your company procedures? I know of no such law.
It would be very unpractical as well, any (low speed) RTO would lead to a taxi back to gate for an inspection.
It is irrelevant that we check reversers stowed during the walkaround. IThat still does not make it 'law' to visually inspect reversers after you used them during taxi.
