I would actually argue that merging is much easier than splitting
something up. If A depends on B, merging B back into A is trivial. But
if B is a part of A, breaking it out of A is a much more difficult task,
as the boundaries of A and B are not so easy to find and the coupling of
the two is much tighter.

I find trying to break things out of perf is very hard to do as the
dependencies are throughout all of perf, and no one seems to agree on
how to do so.
