It can be that. The advantage of it is that guys/girls can be significantly worse than what you would normally consider, but because they have this bonus, and because they have underlying traits and/or star power or something that makes them marketable, or menacing, this gives you a way of pushing them beyond what their base working stats would normally allow and with good booking and momentum management get them over.
Eventually though, you will find people, or develop them into actual workers. And then this style actually becomes a small penalty which at the absolute endgame means you can't abuse slow build, which means they won't be putting on 90s which means they have a ceiling.
This is why I book them the way I book them. They are incredibly nice to have early, meh mid-game, and a hard cap late.
