It's been a bit too long for me to recall what all I was doing here and
what it should've been doing.

Just looking at the files, I was attempting to figure out how the EO
stuff works. Think I had some basic results, but just mostly added a
tracing store to help w/ debugging

Not sure what or how I broke the identical object tests; but I'll look
into them at some later point

Yeah... not a great commit message. t.b.h, I could maybe've split the
commit into more parts; but that would be quite a lot off effort and
would have a pretty decent chance of at least one of the commits leaving
the repository in a non-working state.

For the future, will want to try and commit more often so there aren't
these mega-commits where it's just "a whole bunch of stuff changed"
