Sorry RAT5, but I disagree with you.
An RA is NOT a common occurence, and the QRH in case of engine failures or issues correctly focusses first on SECURING the Aircraft and systems.
Only then, when time permits, shall we think about secondary consequences, like TA, fuel balancing and further intentions.
It is all about priorities, and selecting TA ( and 7700 by the way while securing the aircraft) is NOT.
