I disagree with it.
The editions that got closest to what you wanted were the original 1e and 3x editions. Subsequent editions after 3x haven't been evolving into more fluid and open class structures, if anything we've gone from more open class structures into more fixed and rigid class structures with remarkably little customisation options within said class structures.
And, point buy isn't new, it's been around for multiple editions (at least 4 that I know of), but rolling for stats is still the first method that the PHB gives you for generating your stats.
