@davidgerard Yeah... I actually did that this afternoon, for actual bloody Reasons.
Didn't quite work: eventually I ended up strace(1)ing a process, dumping out the full strings from calls to recvfrom(2) in hex escape form, and printf(3C)ing the damned thing. All to extract a JSON schema that should be documented somewhere but AFAICT isn't.
I hate modern shit. Can we go back to 1995's web, please?
