ferris,
As long as the procedure is in CAA approved JAR-OPS compliant ops manual then those pilots operating in accordance with the CAA approved ops manual will continue to do as I said in my post.
You seem to forget that the response to confirm is simply "afirm" when the proposed information is correct. If one was to use "say again" then that would require you to repeat all the information again. Also say again is appropriate when all or part of the message was missed which is not the case and of course, the ops manual would still require the "confirm" at the end.
Perhaps you would prefer that both pilot remained on frequency and you passed the ATIS on your frequency?
Not advocating the use of the term on calls when both pilots are in the loop but as a tool to prevent level busts in situations where only on pilot is in the loop it is a useful tool which uses very little R/T time.
If you get it all the time it could be that the other pilot is out of the loop for the whole period that flight is in your sector. If that aircraft is below 10,000 and/ or it is a busy terminal area then you could have an argument for it not being a good time to be getting the ATIS etc.
