For example.

My point is, whenever something needs to issue a SEV* fw command,
something adds a silly wrapper and this will become unwieldy pretty
quickly.

If a wrapper is not a dumb one but it actually does preparatory work
before issuing the command so that the caller's life is made easy, then
yes, by all means.

If it is only plain forwarding a call to sev_do_cmd(), then I question
the whole point of the exercise...
