I was wondering the same thing but I sort of see this happening in
my group - mainly because of certain engineers' hesitance to make
branches and check in code. There are some multi-month development
efforts (changes/updates) that have never been checked in anywhere
and the code being passed around manually to the other engineers
that depend on the new code.

A lot of this may be due to past poor tool sets and thus learned behaviors
that do not really make sense.

Knowing what a developer has changed locally - for whatever reason - is
usually not productive and can actually be counter-productive (especially
when it is a trial-balloon type of change or hack to test something).
if the behavior is like I described above, then what is really going on is
trying to make the tool work around bad behavior.

Actually, I have pushed to change-set reviews but this is done within
a short-lived branch. The branch is then destroyed once merged.
This has the added benefit that the change set can be worked on
by more than one person and the review of the changes is rather
easy as it is exactly the same process as the review of a patch or merge.

(This is mainly for larger changes - a spelling change or other such
minor thing usually does not go through the same level of code review)
