Gain vs. power mode for add channels

When setting the power for a connection in PowerMgmt.java, the TransportPCE controller always switches from power mode to gain mode, whether the connection is for an add channel (srg to degree) or for an express channel (degree to degree). The OpenROADM MSA says the following (see "Local Control" sheet):

"the controller can optionally change the control mode to "Gain" which will lock in the internal gain settings which was last used to control the power.  This decouples this controller from all other cascaded controllers.  However, the Add/Drop is likely to stay in Power mode."

One advantage with keeping power mode for add channels is that the device would react faster to e.g. attenuation changes locally in the device. Is this something that has been considered?
