Everything works as it should, I don't see a problem. If I cut off dynamic registrations, a) it would regress against Mach1 b) IBM will rise a ruckus So, this feature was left in on purpose. In fact, they wanted us support dynamics officially at one point, there was a FT item (before FZ). Closing as notabug.
