The "trusting trust" argument is wholly unconvincing for the reasons nickpsecurity mentioned. There are too many moving pieces in this equation already, and piling on "moving to a new architecture" on top of everything else just doesn't make sense.

If your compiler is portable this still means the only thing you need to write is the new backend. [1]: https://www.dwheeler.com/trusting-trust/ https://www.dwheeler.com/trusting-trust/
