Did you miss the context of my reply?

Changing something for an existing user that will have a large impact on 
their user experience does not mean that the new feature 'isn't good 
enough' for them, it simply means that an update shouldn't just change 
it without any regard to the impact that doing so will have on the 
existing users user experience.

For new users, there is no pre-existing configuration, so there is no 
real potential for major disruption of an existing users experience.

Yes, someone who is an experienced Thunderbird user will definitely 
notice the different UI if they perform a brand new install without 
migrating an existing profile, but it wouldn't be disruptive in the 
sense of 'breaking' things (in their mind).
