Just say you had a point helper that had an attachment controller and so it was following the motion of the point cache mesh. If you hide the point cache mesh should the point just stop moving? No it shouldnt, you would expect it to keep moving. The attachment controller knows its dependent on the point cache mesh so triggers the update.
The same should happen for fume, but it seems all the fumefx object dependencies are broken. You can inspect the dependents on a fume grid by using refs.dependentNodes $FumeFX and it will not report any of the objects you have added to the grid. This would seem to me (and I do not claim to know whats going on under the hood) that fumeFX is bypassing the standard max refs/dependent system to trigger updates. I could be completely wrong, or it could be a way fumeFX is coded for speed, i dont know.
All im saying is that as an FXTD working with 15 other FX artists on a job that relies heavily on FumeFX we have found that this issue has caught us out a few times and wasted our artists time. I have a scripted work around so we can work the way we want now, but I just thought id share my issue.
