They did give it a name, they scuffed their feet a bit, avoided eye contact, and mumbled ' Jaguar '; for those unaware, have a look at both airframes etc.
Just as the Harrier / P1127 was borne from the P1154 project cancelled at the same time as TSR2, the difference being the Harrier worked.
Both the TSR2 and P1154 would have been very expensive disasters if they'd gone ahead, which might be a lesson, though probably only relative to those times.
