I'm not so sure. The much-referenced delay in spooling up (and the reference to earlier problems in the A320 testing regimen) referred to slow spool up at medium to cruise altitude, and thus a completely different area of the flight envelope compared to the position of the Habsheim jet.
The consensus as I understand it was that allowing high-bypass jet engines of any type and on any airliner to spool down at any point of the approach was a big no-no, and pilots of the calibre and experience of those in command on the day should have been well aware of that fact.
