This changes the data sent by OSM_EVENT_ID_LFT_CHANGE. I think this is a dangerous precedent. Even though plugins must be coded to specific versions of OpenSM I don't think they will fail to compile with this change and users would get random behavior when they try to use the event_data passed. I think it might be more appropriate to define a new event id say OSM_EVENT_ID_LFT_BLOCK_CHANGE.
