Correct, delaying releasing 78 for 1-2 months isn't an option.

It seems to me the idea you mention above is a very good one, give users 
an opportunity to opt out when starting up 78 and be able to go back to 
68.   But we are now past string freeze, so we need to very quickly 
navigate that issue.

I would not include dates - dates can change.  I wouldn't even mention 
releases.  We can communicate that information in the existing enigmail 
add-on when we know everything is ready.
