Right, as I said to Mark earlier:
"Yeah, the moment something starts using it, it is ABI. The good thing
about it is, though, that it can get stuff appended to it, just like
tracepoints get fields added. And tools should be able to handle parsing
appended lines fine. Removing lines OTOH is always problematic. But
we'll make that append-only."
It is basically the same principle as with tracepoints where we can add
members easily.
