AFAICT, there is no known way to confirm a guest architecture supports specific features. In libvirt today, all of the feature checks are done against the host architecture. Additionally, a quick check could validate, but I see no harm in adding <acpi> and other features into the template xml (or the host detection), guests that don't support ACPI or the other features will ignore them.
