I don't know if you are only referring to the current situation in spain. I totally agree with you on the first half of your post, but usually if I ask you a rolling take-off is to expedite the traffic flow, to help you avoiding delay, the same if I ask you to "expedite vacate" and so on. a met condition/wind report is good for other pilots.
Then pilots are able to "give ATC a pretty hard time" anyhow
