Frankly, as someone more interested in emulation than virtualization, I have been occasionally unhappy that most of the energy behind QEMU goes to virtualization. Some of the things QEMU has done to better adapt to virtualization do not translate well to the emulation use case.

This is not true, for example a lot of the work to enable concurrent emulation of multiple CPUs started on the virtualization side. It is also mentioned in the article that both emulation and virtualization benefited from the innovation.
