Agreement, excellence in one domain does not confer it to others. If you've ever worked with researchers, you know for the most part they are not engineers. This is bad advice / prediction by people with hammers imo.

OCI is a good choice of reuse, they aren't having the agent reimplement that. When there is an existing SDK, no sense in rebuilding that either. Code you don't use should be compiled away anyhow.

Except it's not 'once' though.

In order for it to be 'once': all hardware must have been, currently be, and always will be: interchangeable. As well as all OS's. That's simply not feasible.
