It defeats _one_ of the purposes of using Docker for development.

I expect that the official M1-supporting Docker Desktop will eventually, given a dual-arch image, allow you to choose which architecture to use. (One would run natively, the other under emulation)

There are situations where I'd use this feature, but 90% of the time I'd be fine using arm images locally and deploying x64.

(I could also imagine this working the other way -- an x86 dev machine and an arm deployment target -- which I think to some degree is supported by Docker today)

At least on AWS, it's slightly cheaper to deploy ARM servers. Look for this problem to also get solved on the server side by more ARM servers being put into production.
