A spurious network event that gave up security properties SHOULD NOT quietly give those up on behalf of the user.

I betcha browsers soon retry with their best version, before decided when/how to fallback.

Network hiccups happen all the time. For plaintext protocols they are benign. For security protocols that would silently give up features they are not.
