Point taken, but I think I agree with the common view at the moment that any turn keeping fire from blowing onto the fuselage is beneficial. On the flight deck, especially with the current locked door policy, we really have no idea what is going on in the cabin, and whilst the pilots are making their mind up, there may be drama going on already at the rear they don't know about. This was the situation in Manchester where fire was being blown onto the fuselage from the severe fuel burst. If you have the capacity before you stop to work it out, it won't hurt doing it, and may take a couple of seconds- maybe not quite like the spectacular handbrake turn I did the other day in the sim! The mantra is 'in a headwind, any turn towards the fire, in a tailwind, any turn away'. I've been briefing at the start of roll which is the critical in the event of fire and asking for a reminder. I think it works.
