The real test would be in the coming weeks when a lot of the original daca recipients are set to expire. I'm praying that they are not that callous to let thousands of work permits expire.
The easiest thing they could do if they don't think they can get to renewals on time is to simple send out letters like the one they send out for reminder notices saying something like whoever holds this EAD is allowed to work 2 or 3 months past the expiration date on the card. That doesn't cost a lot of money and solves a lot of our problems.
