All sound like a very general type of statements you could say anytime and mean nothing at all by them. So I'd feel my T is not listening if he were to use any of them/or similar statements.
I hate validating (feels patronizing to me), rephrasing/summarizing/parroting (why would I pay for stg any child can do) or too obvious mirroring (certain level is fine, everybody does that). In fact any time I feel my T is using some therapeutical technique I call him up on it. Fortunately, I found one who can oblige (most of the time, anyway).
