This is what I would prefer also. However, as far as I've understood, it's not what Markus implemented for OpenSSH.

If Markus and Damien wanted to implement this - that both sides presenting ext-info-{s,c} should reliably lead to both sides sending SSH_MSG_EXT_INFO - then I would prefer to modify the draft this way.

However, it would be counter-productive to knowingly specify behavior different from this major implementation.

Sounds ok to me.
