Sure, but for it to be anonymous it should not contain the sender's IP address. That probably means an UDP message with nulled source ip, which runs foul of many ISP's egress filters (and rightly so).
So, realistically speaking, there is no such thing as an anonymous ping. Or am I missing an obvious solution here?
I think only 1 type of telemetry shouldn't ask for permission, a quick, anonymous ping to say it's been installed.
