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.
