It's not easy to program in a million, but it distracts (from your other well made point) of a usable PS.
 
As a neophyte enthusiast I think a design should separate each of the sub-systems of the PS onto separate boards. Then use interconnects.  This way might be more expensive and more work but it also would provide a path to augment with new features later. And also allow replacement of one sub-system that had to be altered due to problem parts, like the entire LT308x series.

I lack the knowledge to know if this is a feasible approach but the feature creep is definitely a death trap. And I think a modular (based on the PS sub-systems) design would keep the feature creeps quiet as it would allow future additions.

LukeW:
Perhaps the 0-40V 100W power supply published in this month's (and next month's) Silicon Chip might be of interest?

Marco:
How hard would it be to modify the feedback loop in one of the many One Hung Low Meanwell clone power supplys? (In and of itself that wouldn't give a useful bench supply, but maybe with some filtering and a linear regulator.)
