Nat Sakimura:

It may be worthwhile to point out that all JWE algorithms are integrity protecting as well. 

Proposal: 

Add the following as the second paragraph. 

NOTE: All encryption algorithms used in JWE are AEAD algorithms that protects integrity so there is no need to oversign the encrypted payload separately.
