Yes the user space is not yet released. However I think module parameter
is not considered part of the linux kernel uAPI and there are no guaranties
regarding not changing or removing or change the semantics.

Obviously we don't want to brake anyone config file or script, but that's more
like courtesy than hardcoded rule. Currently nobody except Intel and it's
partners are using intel_vpu and all user should be aware of the change.
