Remembering the Mac ARM transition pain wrt Docker and Node/Python/Lambda cross builds targeting servers, there's a lot to be said for binary compatibility.
You want to be able to replicate the build in your local dev env. And you're not always working on a mature project, you first get it working locally. CICD tends to be slow and hard to debug.
Sure, but why does the developer environment have to be the same architecture as in production? Think of it as ahead-of-time binary translation if you want to.
These days, even fairly low-level system software is surprisingly portable. Entire GNU/Linux distributions are developed this way, for the majority of architectures they support.
90% of those problems effect people like you and I, developers and power users, not "regular" users of machines who are mostly mobile device and occasional laptop/desktop application users.
I suspect we'll see somebody -- a phone manufacturer or similar device -- make a major transition to RISC-V from ARM etc in the next 10 years that we won't even notice.
