I disagree completely. I've worn several hats at every job I've worked at, each one demonstrating a different skill set. I will reword, change the order of, or even completely delete or swap out bullet points under jobs to highlight the skills that a particular req is looking for.

If you're "just another developer" applying to a "just a developer" req, then yes there's probably no reason to tweak. For anything else, you should absolutely be reconfiguring your resume to highlight your relevant skills.

I disagree with that assertion. When looking for my current position, I had a much higher response rate when each resume was tailored to the position.

Tailoring, in this case, meant relatively minor tweaks - if it was a more engineering role I'd highlight those skills and contributions whereas with the more data science-y roles I'd highlight more relevant aspects. I think it's very arrogant to think that a single resume is appropriate for every job application.
