Ambient does not need to be updated, running an ABox-Ambient in an otherwise completly QBox-MorphOS is absolutly possible.

There is nothing in Ambient that would make sense to be updated in a PowerUP-kind AMP setup.

There is nothing to be updated in Ambient with a QBox that has access to (or controll over) GFX or the filesystem.

Once all these steps have been completed (aka "in the year 2525") it might make sense to recompile Ambient for QBox which will surely need some changes on the way.

So yes Ambient is 100% irrelevant for the current discussion about implementing AMP as a basis for a future QBox.
