I can understand what you're saying, but isn't that really an issue with 
the rapid release process and not with whatever version number format we 
go with? I think the fact that new users already get security & bug fix 
releases and they know when they do, will mean they are already used to 
another new version turning up.

I haven't covered this yet for Thunderbird, but the plan is to follow 
what Firefox do - they have already have a process in place where they 
look at add-ons for interface uses that have changed, and bump the 
add-on compatibility version if none are detected. I believe they will 
be looking at incorporating user feedback as well (I think I saw some 
references to the add-on compatibility reporter being used to aid this).

On the whole, I don't think we'd be breaking every extension every six 
weeks, so it is a lot less work for add on developers to do than first 
impressions might give. So far I believe the add-on coverage for FF 5 
from the automated bump is somewhere around the 75% to 80% mark, which 
IMO is a pretty good start.
