I think the "safety" of "familiarity" vs pushing the envelope of what we can do technically are different things. We used to build brand new computers and operating systems from scratch specifically for these types of things.
The risks are indeed high for managerial staff. I worked at a large quasi-government place. "you won't ever get fired for using Microsoft, Oracle, etc" was a tagline we heard often in non-critical systems, so I imagine there would need to be some major technical reason to switch.
