Well, it depends on the workflow. You are making the assumption 
that everyone is using your workflow, and you are judging them 
based on that false assumption.

In my workflow i never miss .rej files because i use tools that 
_do not allow_ rejects to occur - only if i intentionally force 
them. So i cannot "miss" any .rej files - i generate them very 
consciously so all my attention is on them already.

For example i never use the naked '/usr/bin/patch' tool for 
example (which generates rej files without any forcing) - i 
consider that practice a serious workflow error for various 
reasons.

In fact i prefer to keep .rej files around and not remove them, 
to have some minimal history and to be able to see recent 
rejects and if there's a problem i can still reconstruct whether 
i did a patch conflict resolution incorrectly.

What _can_ happen on the other hand is for a .rej file to get 
into a git repo accidentally - while nobody ever would want them 
to get into any git tree, ever.

So ... by all means this is a sane workflow, and Jeremy and 
Alexey i suspect has a similar workflow as well.

Anyway, the .rej problem can also be solved via the pre-commit 
hook - but unfortunately there's way too much sub-par commits 
from elsewhere in the tree, making consistent use of the 
pre-commit hook quite a challenge.
