I tried out the bulb ramping with 2.3 RC1 - here's my result.. pretty good I think. Some deflickering with LRTimelapse, I didn't put too much effort into fixing the flicker but it did really well by itself I think. It was a basic 3 second interval on the Stage One dolly, though the ramping didn't say it got beyond 1" on the screen, some shots felt like they went for 2-3 seconds so it was a bit weird near the end, the dolly was moving as the shot was being taken at some points. (I don't have the move/shoot/move set up yet, still waiting on my PC sync cable so the dolly was acting independently to ML's intervalometer).
