@Greg: Thanks for info. Is this one of the next steps in framework changes? Or is this a thing for my great-grandson to worry about?[/quote]
We make changes to the undocumented parts of the framework all the time, mostly to fix bugs and improve performance, but also when new features are added.
I can’t give you a timeframe, but if you do report a bug or other problem and you’re calling into the undocumented parts of the framework, we may just say "you’re doing something unsupported and we can’t help you. "
