Agreed to your argument about the temporary-evaluation job being only possible for a junior developer and not to somebody that already has a job. However you should also add to them all the cases of senior developers without jobs (yes, such cases do exist) -- a temporary evaluation job is better than nothing. Senior developers that have jobs won't take the risk of leaving their current job and going to an evaluating position. But these people also shouldn't be interviewed -- since they have already have jobs, a talk about their previous projects and work should be enough for anybody to decide if they are good enough.
