A corollary of that argument might be that we should remove any feature 
from TB that is used by 7% or less of the users. But there is a problem 
with that.

How many features does the average user actually use? If  the product 
has hundreds of features, and the users are fairly randomly distributed 
in use of the features, than if you were to remove all features that 
less than 7% of the users use (which would probably be at least half of 
the features), then I would guess that the statistics would show that 
you would affect >99% of the users.

So there seems to be an underlying assumption that the vast majority of 
users use a small subset of core features, and only that subset. I would 
think that reality is that the vast majority of users use at least a few 
rare features that would affect them severely if removed.

This is also a critical marketing question. Is Thunderbird positioned as 
easy-to-use, but with limited features, or  are you trying to be the 
application that can do everything?

But I guess we can continue this discussion when some real data from 
Test Pilot exists.
