I've worked with people like this - they're usually very dogmatic and won't defer to the status quo. This can be useful because they'll find low-hanging fruit like this that everyone else just accepts.

Long-term I find them annoying to work with because they seem to chase progressively higher cost/lower return changes. Especially in a startup context they're obsessed with being technically correct over building something people actually want. Green field stuff takes 10x as long as it needs to because they refuse to release something quickly and iterate.
