This page tells you about all the features Qemu has and will get and/or lose in the foreseeable future.
Primary and Secondary
A primary feature is a feature that is actively maintained. Breaking it by introducing new code is a no-go.
Secondary features are there and work, but either there's no active maintainer caring enough about it or people don't deem the feature important enough to declare breakages here a blocking issue.
