I believe IBM Debug Tool uses this. But you're right that there is no API provided. And given the amount of time that has gone by and the fact that, to my knowledge, there never has been a formal request/requirement submitted asking for such an API, the answer to your question (unless such a requirement is submitted) is, in practice, "never". And a new requirement might be declined unless there is significant business justification that would make this a good candidate. We all wish that we were in a world where "should" would match "it is", but there is always a resource tradeoff to be made between competing items and the question has to be answered of what would you the customer (and IBM) be willing to sacrifice getting in order to get "this". "Should" only takes you so far. That should be apparent to all (but many discussions on IBM-Main do not seem to take that into account).
