The ball race bearing in the drive end controls the endfloat on A7 dynamos, so there should be none or a tiny amount if the bearing isn't totally knackered/loose on the armature spindle/loose in its housing. I would definitely want to sort this if it were mine. Even if the endfloat didn't get worse in use, the amount already there will cause ignition timing scatter.
