Angular 1 -> 2 is an actual "major release". "Rewrite all your apps from scratch" major.

But starting from Angular 4, the "major version number changes" doesn't mean a major effort to update. There's a decent chance that 4 -> 5 -> 6 -> 7 etc will work without any code changes. But as long as there is a backwards-incompatible change, no matter how small and in how obscure submodule, it requires bumping the version number according to semver.

Most enterprise users will probably skip multiple versions between upgrades, just as they skip Ubuntu releases and Django releases and Rails releases and so on.
