That would be rather useful.

We could still be flexible about experimental tracepoints (they dont
hurt), but apps should stick to ABI bits - or at least not complain when
non-ABI tracepoints change for good reasons. (arbitrary, avoidable
changes are still bad obviously, regardless of the type of the
tracepoint)

We'd be more stringent with marking tracepoints an ABI.

So yes, this would be lovely to have.
