QEMU, like most open source projects, relies on contributors who have motivation, skills and available time to work on implementing particular features. They naturally tend to focus on features that result in the greatest benefit to their own use cases. Thus simply declaring that an open source project, must support something won't magically make it happen.

This error doesn't occur with an older QEMU (I tested QEMU 2.12 on Ubuntu Cosmic) or different architectures on QEMU 3.1 (I tested x86, x86_64, arm, aarch64, s390x). Also it didn't help to use an older Alpine Linux (I tested v3.8). So I think it is caused by a bug in QEMU rather than the distro/package.
