I can imagine plenty of circumstances where someone might want
by-protocol indications of service, rather than the relatively basic
link-test that ICMP provides.

Another vote for iperf....

Is there a reason that standard ICMP pings aren't appropriate if you just want packet loss info?  Obviously every platform worth using has ping built in.
