My experience is this obvious perspective vacates with any level of moral maze. The hiring processes kind of require it --> getting headcount approval requires defining a role and arguing how it will lead to better outcomes and then finding/interviewing candidates takes months of time. If your priorities shift in that time...well now you have to shoehorn whatever candidates you get into the role definition you gave before even though you know at that moment they'll be working on something different. And then priorities shift again before they start. Leaving you not knowing what they'll be working on, but also certain you'll need extra hands on something sooner rather than later... AND SO: "give me a smart generalist that specialized in these 8 technologies that make up the entirety of our product" becomes the only viable hire.
