If we want an automatic way to specify something you requested ("give me something that's going to work") we either have to change the definition of the max model for alla rchitectures or introduce something that really matches the "no -cpu specified" - e.g., "best".I don't strongly object to 'max' including deprecated features, but I do definitely object to 'max' including by default any experimental (x- prefix) features. Those should never be enabled (whatever the '-cpu foo' name) unless the user has specifically opted into them: that's the point of the x- prefix. We need to be able to tell from the command line whether it's got any non-standard weirdness enabled.
I'll let Eduardo respond to that, as we don't really have experimental features on s390x, especially under KVM ("host" corresponds to "max").
