With every big rebuilds we get new breakage stories. It seems like
it's the norm nowadays rather than the exception.

I am wondering if it's really only the users that are to blame.. or if
Arch is also to blame. Or if Arch was supposed to be an elitist
distribution and is victim of its success.

More importantly, I am wondering if the sodepends/soprovides proposal
would not actually be a more complex solution than the
libfoo2/libfoo3/libfoo4 way.
