That's the theory and I am aware of it (and I guess eric knows bonsai too).
In fact, I documented the whole ~650k diff for the thunderbird
1.0.2 to 1.0.6 transition that way. I don't want to look at it again,
but there are definitly checkins that are neither documented to fix some
bug, nor are they obsolete. Not all checkins are directly named that way.
For example, checkins needed to fix some security bug are often documented
as a bug, called a blocker (but not always).
Just start to do it on your own and you will soon realize that this whole
thing is not as simple. The only guys that can do it properly are the mozilla
developers ... by documenting and aggregating patches that are
actually applied for each single bug or mfsa. In this way they might even be able
to prevent ABI breakage by accident, like with thunderbird 1.0.5.
Cheers,
