I suppose “management complexity/demand” might indeed be a bit too narrow, but either way it just feels like you’re basically trying to define “core competency-ness” as “difficulty of outsourcing this task [whether for management demand or other reasons],” in which case I think it would make more sense to just replace “core competency-ness” with “difficulty of outsourcing this task.”
My worry is that trying to define “core competency-ness” that way feels a bit unintuitive, and could end up leading to accidental equivocation/motte-and-baileys if someone who isn’t familiar with management theory/jargon interprets “core competency” as important functions X, Y, and Z, but you only mean it to refer to X and Y, reasoning that “Z is some really core part of our operation that we are competent at, but it can be outsourced, therefore it’s not a core competency.”
