Authorization is NOT required for Class E extensions of class D airspace, see FAA memo.
I checked the latest version of airmap and it shows it restrictions correctly, at least for my local airport CRQ, Carlsbad, CA which is supported by LAANC.
Latest stats on Waivers approved by FAA. No surprise almost all are for Night operations. Anything else expect to spend a lot of time and effort and still get rejected. FAA is close hold about processing stats, such as what percentage are approved and processing times
