It wasn't an exciting feat, and they chose to make it worse (while other, more popular feats just got the +1 stat slammed on top of them). It is utterly pointless to pick now (get +1 average dmg with one of your weapons). Even if we ignore this playtest's weird 'draw/stash a weapon before/after every attack' bit, needing a feat just to draw both your weapons was always a terrible idea.
TWF was fine for lv1-4, and still is. But then... it doesn't scale, other fighting styles are given actual lv4 weapon feats, only one magic weapon is not enough for your lifestyle, there is a chance that they'll clarify that drawing during attack still counts as your item interaction for that turn... it's been meh for a decade, why stop now.
