As someone who's been a hiring manager for around 7 years, I agree with you, but note that the people who screen resumés before they even _get to you_ very well may be looking for those references.

For my own resumé, I include the stack used at each job which I feel strikes a fair balance.

That's what I always did too. Then I removed it because I wanted to focus more on the kind of problems I solve rather than the languages I've worked in, and recruiters complained, so I put it back in.
