Yes. The other one doesn't have a restriction on amount of use. But at least I was said only the person who needs to exit or wait outside +1 caregiver will get to do so(with an exception for 2 caregivers in a judgement based situation). The rest of the party, whether it 2 ppl or 10, will have to wait in standby and once the section of the party in standby gets to merge; they call the members of their party outside and those 2-3 ppl wait in the LL to meet up. That's the system given to CM's that can be offered by the greeter. It's 100% a longer wait than just going in standby, so it's designed to be used only for those who actually need it.
Rider swap is still there but is now for everyone to use if they want.
Exiting the attraction and getting to come back is not as well defined and aren't new systems. It's more just that you will have to come back in through the LL or just wait back in standby depending on how far into the line you were. Your party can wait before getting loaded or at merge for you. Or if yoy needto exit right before loading, you probably get to comeback through the exit if you communicate. Very similar to what already happens informally. Barely anyone does this option right now. It really is only when you need too. And they are betting that the number leaving and claiming emergency won't spike to a huge degree because it's wildly inconvenient. I.e, only for when you actually need to.
Thats what CM's were essentially told. And to be as helpful as possible. They were also assured that managers and leaders would be at their beck and call for the first few months to resolve complex situations.
