Just because it is a side effect, doesn't make it "bad". Now that
Subversion has matured past some of it's original design goals, I think
it is useful to revisit some of these (unavailable) features again.

I am not suggesting to re-implement the current design to make this
information trivial to get, but to potentially provide a way to
gather this type of information from the current system and provide
it to the user in an easy to get fashion. This is why I'm exploring
tying some hook scripts into a secondary database to generate the
information I am seeking. Sorta like what was done with merge tracking
originally.

I suppose in a small way, I'm trying to gather requirements for how
others would like to be able to better visualize file history, since
I realize I haven't experienced all development techniques.

Evil twins only occur when the file name is considered the only unique
part of the file, and ignoring parentage, etc. It is something
that definitely needs consideration in any design.

And we do use Change Management software as well. I disagree that
some additional visualization of file history is unreliable and
this information should only be available in a Change Management system.

I have been following and testing the merge-tracking stuff, and it
wasn't really meant to solve this particular problem, nor do I think
it should have been a design goal of this feature.

Merge tracking is definitely a prerequisite to any complex development
process, and any advanced file visualization will need to include
merge information, but I don't think it can replace it.
