I think it can work in modern games, but doing so feels like an old-school frame of reference.I think that can work out just as well in modern games. Most 5e D&D classes are mechanically built around a couple stats in a transparent way (similar to most classes throughout various editions of D&D) and there are mechanically good options for most stats as a primary. So if you roll a high Charisma for instance you look at Warlocks, Paladins, Sorcerers, and Bards. Its just a question of where you want to build your character concept from.
Most modern games use Playbooks, or something similar to them, which are definitely concept first. Even a modern crunchy game like PF2 only has "choose ability score" as the 5th stop in the character creation process, after concept, ancestry, class, and background.
