I’m ambivalent about this. One one hand, I think 1+Str damage is too weak to be worthwhile in most situations. On the other feel like 1d4 unarmed strikes really devalues simple weapons like clubs and daggers. I kinda think maybe it’s fine that an unarmed strike really isn’t a viable offensive tactic for those who aren’t specialized in it in some way (such as the feat, fighting style, or monk class). And especially with shoves and grapples getting rolled into unarmed striking, I think it might be fine for unarmed combat to be more about controlling opponents than damaging them unless you spend character building resources to make your unarmed strikes more lethal. But in that case, 1d4 seems pretty weak for a whole feat investment, even with the small boost of rerolling 1s. So, after talking (err… typing) through it, I think where I’m at is, leave the basic unarmed strike at 1+Str, but make the feat (and possibly the fighting style - we’ll have to see if that gets an update) a bit stronger.
