I agree on almost all fronts.
The person I replied to asserted that all timing attacks are theatre, which I disagree with (and, evidently, poorly communicated my stance). Perhaps they did not mean the entire class of vulnerabilities which rely on some sort of exploitable timing difference, but only those that require privileged (or physical) access. In that case, I still believe it is foolish to completely dismiss them simply for being a 'timing attack' (and therefor theatre), but I also believe it is foolish to blindly follow mitigation recommendations without analysis.
