No, it doesn't address it. It contains it.

As source code, the license issue is hard to contain. But linking against a
system library has relatively limited license implications. LLDB does this
and we've done it elsewhere. It is a relatively constrained and well
understood thing compared to embedding source code.

Yeah. Its something that we avoid for the convenience reasons among other
issues.

As for how to weigh it against having to implementing something that
already exists in the world, dunno.
