However, I talked about it with sergiusens and we are unlikely to change this.
(1) The behavior would change for any existing users.
(2) As you are seeing here, --target-arch support is broken in other ways, and rarely accomplishes what the user is hoping for.
Due to these issues, Snapcraft has disabled --target-arch for core20.
We do understand the value of targeting other architectures, and we hope to provide a well-supported solution in the future.
Taiten, I agree that would make sense :)
