I agree that inside an atomic, small-ish, teams titles should be meaningless and skipped.

But in bigger companies there is actually some use to the title, when you look someone up in another team you want to know who are you talking to in advance. From my experience this is not something rare or esoteric an actual need.

Add to that the fact that somekind of leveling is usually needed, both for salary ranges and for promotions, so even if you skip the bloated title you'll still have someone's level.
