Remember the TSR2, anyone ? (and I think, the F-104, as well as the Buccaneer).
Way back then, the problem of getting good-enough low speed handling combined with high-speed performance was solved by flap blowing. Seems simple enough, till you think of all that interlinked pipework and the engine-out case, which could well have needed max. thrust on approach from the "good" engine and would probably not have been all that comfortable for the driver.
Tornado, the TSR2's "replacement", took the swing-wing approach, which seems to have been the better answer, despite the mechanical complication. Whether one or 'tother was the "best" solution in service; I leave to those who have experience of both, in flight and maintenance ...
Just a side-bar for the main thread ...
