Long ago we had this whole discussion and agreed to go with the conceptual memcpy like solution to reorder the bits to not have a gap. I still think that is a good decision. 

In practice an implementation could avoid this by how it structures the data inside internally. 

The memcpy is not a relevant performance hit for something like a SFU and would be even less of a performance hit for most other uses cases. 

We should not use any non AEAD ciphers on any new protocol work, it just leads to too many security nightmares.
