I was assuming SuggestedAckDelay would replace MaxAckDelay, but I agree it adds some complexities.

Maybe the sender controlling NumPacketsBeforeFastAck(?) is sufficiently good for now.  It does avoid complex issues about how small an ack delay the sender can request of the receiver.

We keep wanting the ability to update MaxAckDelay.  Does it make sense for the frame to include both an updated NumPacketsBeforeFastAck for the receiver to use as well as communicate a new MaxAckDelay?  If so, that's feeling more like it should be UPDATE_TRANSPORT_PARAMs, but we can discuss that further.
