As I recall there were three proposals for resolving the padding bug in TLS

1.       An extension for Pad First (i.e. padding before an otherwise standard TLS mode of operation)

2.       An extension for Encrypt-then-MAC (i.e. this draft)

3.       The replacement of each existing cipher suite with an equivalent AEAD one

Was any consensus achieved as to the best approach?
