A standardized hammer can just be a carpenter's hammer, though. Putting a nail pull on the back side is making it opinionated in a way that gives users access to a tool that they may not have thought of if they built their own hammer, but very well might appreciate having.

This isn't a defense of enterprise applications, though. They're more like a shed fully of rusty tools with a thirty different coping saws blades and not a single handle because corporate policy only allows for you to have a handle if Joe from accounting says you can, but why would he when his VP confidently said you can just hold the blade between your fingers.

You forgot to mention the IT Security team locking up all the screwdrivers to prevent potential cross-contamination with hammer usage.
