My immediate reaction is that it seems inconsistent with the rest of
merge behavior.  Why would add/add behave this way but edit/edit not
behave this way?

Would this behavior be configurable or unconditional?  I suspect I
would want it turned off in my own use.

On the other hand, in the case of wild difference between the two
files, skipping the two-way merge and just writing one of the versions
to the worktree (like we do for binary files) sounds like something I
would like in my own use.

Can you add something more about the motivation to the commit message?
E.g. is this about performance, interaction with some tools, to
support some particular workflow, etc?

Thanks and hope that helps,
Jonathan
