Yep, this is just a ploy to create a PMC that actually has no skill workers in it. You just shove MBAs, nepos, etc into these roles and just have them gobble up some managerial course which is often nothing but: delegate, CYA, and 'manage expectations.'
I dont think we need to go back to the old ideas of The Manager who is Above It All and Doesn't Get Their Hands Dirty. At least at middle levels.
