I'm not happy with making it easier for downstream users to build
incompatible libraries. The versioning guidelines that we set up at
the start create a very strict, *and* a very high expectation of
compatability. I don't want to see that trust lost, or a set of
caveats introduced, through a way to toss symbols from our libraries.
We can tell people with a perfectly straight and honest face, "Upgrade
to the latest rev. It is Totally Compatible." Any questioning around
that statement is damaging, I believe.
