Well, actually, I consider the entire 'messaging' part of APRS to be
totally broken and an inappropriate waste of bandwidth. I won't digi
message packets, even if they originate locally.
APRS is a broadcast telemetry protocol. Any attempt to graft a
point-to-point message onto a broadcast protocol is like carrying on a
private conversation with bullhorns. I won't do it.
