I will take a look.

Unfortunately, it won't be quite simple as I have to modify subscribed events depending on which subdriver is loaded if we are to avoid unnecessary event calls.

Main serialIO driver is subscribed to EVENT_CONNECTION_CHANGED and I need to respond to EVENT_CONFIG_SERIAL_CHANGE.

I'm happy for you no add another subscription to the serial driver. The subscriptions are bits that can be ORed together.
So the serial driver would have

    .subscribe = EVENT_CONNECTION_CHANGED | EVENT_CONFIG_SERIAL_CHANGE

I don't think it will be a big deal responding to the both events as they are both very infrequent.
