There are only 9 fields defined so far, in contrast to the dozens of standardised header fields for HTTP, and those 9 are all kind of integral to using D-Bus - there's no general metadata like the HTTP Date or Server headers. So I might guess this would be a tough sell, though it's not up to me.<br></div><div><br></div><div>Have you come across specific scenarios where something you're tracing is using D-Bus messages and you want to follow them?
