Are there any reasons not to change the existing implementation of Boost.Swap to Ion's version?

You may find it a silly argument, and it goes back to these dependency graph discussions. If you look at the dependency report, like this one http://www.pdimov.com/tmp/report-d5ca5be/module-levels.html It says Boost.Core is level 2 (so, fairly primitive) while Boost.Move is Level 6.

It's in fact not a silly argument at all. Boost.Core is explicitly not allowed to acquire new dependencies - this was the reason for creating it. We can in principle extract Boost.Swap into its own module though.
