I'm going to go out on a limb and say "yes."
An undocumented requirement, but still...

Or maybe because you don't work in a company where the lawyers can't
don't like complication, or because you can't see how having one
exception causes pressure to allow more exceptions.

Reduced, but IMO not acceptable.

We may have to do that if we can't get the uBlas authors to change the
license and we can't come to a different consensus, but I would not
like it. It's a wart, and complicates makes legal analysis of the
implications of using Boost.

I can't speak for them. My goal is to remove the barriers to adoption,
not just keep them moderately low.

In some cases, they don't trust the developers. uBLAS would actually
need to be removed from the code to which they have access.

I don't see how that helps. Lawyers don't care about namespaces.
