" * The 10 minute FCC ID is only required during an exchange, not continuously. The largest issue with depending on the AX.25 frame is that many stations don't use FCC callsigns for their AX.25 address. I don't have a strong feeling on whether stations should be regularly using tactical callsigns, but they do need to somehow stay legal."
Technically, to stay "legal", there is no requirement for a callsign in a packet. The *station ID requirements* can be satisfied by ID'ing on the transmit frequency in CW, or other means.
