"Most people" depends very much where you are, and "feels outdated" is entirely subjective; I know several people who have abandoned 5-card majors as obsolete. Good answer though.

There are plenty of systems that open on 4-cards, I myself play one, and that is not very uncommon here. 4-card systems are commonly used to teach Bridge. Most people prefer 5-card major though, and 4-card major feels outdated these days.
