I knew there are bunch of different approaches to implement what I need, the one I prefer is to use enabled=False/True but by doing that we are moving that feature (in my view it belongs to the scheduler) in the function code. In that case, I have to reinvent the wheel, actually I have also to hard core it, for each function I have to run in that manner. Moreover, I don't have much control. I can create a wrapper to flip the enable=True/False, but at that point, the wrapper could be placed in the scheduler, by setting enable=False before executing tasks defined as 'concurrent=False'? isn't? I agree with you, this is not a corner case, and to be honest, I also need tasks dependencies for other elaborations :P
