That's a great idea and it articulates something I have thought about the whole "use boring tech" things (which I support). It doesn't preclude letting people use the shiny new thing. You can always let them plug it in and use it. But the core of the system should be as simple as possible and based on thoroughly understood tech (from the point of view of the team in question/accessible labor market).

I tend to discuss things in terms of the trunk, branch, and leaves.

Mostly in that the leaves of your system (parts that nothing else connects to or builds on) are generally a low risk place to try new things sometimes. If you do run into any intractable issues, it’s also an easy spot to pluck it off and replace it.
