It's easy to program in a million features, but it's all completely useless when the power supply isn't stable.

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.

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

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.)
