With 2.8kHz of bandwidth, the requirements to obtain a license to transmit, and the restrictions on commercial use in the ham bands, I don't think your fears are warranted. I definitely think the ham bands would get more active for data uses, but I doubt they would get flooded with newcomers. You must already broadcast your call sign at a regular interval when transmitting.
