First: Hide for my ranger was an Action, not a Bonus Action.
Second, every time I attacked an enemy from stealth initiative was rolled for the attacking character and they ended up out of stealth.
Third, and perhaps less significant in my book, is that though it is still possible (as we saw in the PFH) to independently stealth our party members and get in one free attack, I didn't manage in my playthrough to trigger a surprise round, so I did wonder if that might have been removed to balance the potential free attacks from each party member.
