I think that #2 might not happen as often if Homebrew better conformed to a "UNIXy" philosophy. And to Apple's philosophy, because there is a sort of mentality to how they operate, even if you can't predict exactly what they'll do.

MacPorts hasn't had as many of these issues over the years, and I suspect that's largely down to mindset. Broadly speaking, MacPorts seems to have "first, do no harm" approach to almost everything. They don't install files in directories they didn't create, and they avoid depending on systems which are out of their control.
