Which means to tie down it I think. Once we do have a good enough format those bits need to be locked down, with a way for adding new attributes (either entirely new or better replacmeents for existing ones with leaving the old ones in place for existing userspace).
In addition to the format description people have also asked for ABI tracepoints which would lock down the actual trace format in the the same way (only addition of new fields without removing or changing existing ones). For this to be actually useful some trace buffer also needs to be exposed in an ABI-stable (that is non-debugfs way).
