If it used to work, then there was some other kind of bug because the infrastructure doesn't exist for this to work properly yet. It is high on my list to fix. I have one higher priority item, but after that I'm going to fix this. However, the fix probably won't be in the Mstone-4 release.
I'm sorry that you're finding this bug limiting. Changing these kinds of things late in the release cycle is a trade-off between making the platform featureful and stabilizing something we can release. The ideal situation, of course, is to get things right the first time, but I screwed this one up. Thanks for your patience.
