I get that, but even if titles were an amazing proxy for skill, that will only correlate with some subset of skills and say nothing about the rest (e.g. some staff engineers are amazing technically and only pretty good as team leads or vice versa). Even assuming that title correlates well with some notion of skill, there are organisations which won’t allow someone with Fancy Title to make a decision requiring skill C if they’re bad at it - and some would have no way of stopping them.
