--- Comment #1 from Damien Miller <djm at mindrot.org> ---
Sorry but there is zero chance we will offer this as an option. The
version number is used for a number of compatibility tweaks and bug
workarounds, so removing it would greatly hinder our ability to
interoperate and improve the protocol over time.

I'd also say that your security advise is bad: hiding the version
number doesn't prevent an attacker from attempting exploits and doesn't
even prevent the attacker from learning the version of software in use
(protocol fingerprinting).
