Yes, I agree. Extracting it as Boost.Ref makes more sense.

Currently Utility depends on SmartPtr anyway, although you are correct that
checked_delete has nothing to do with SmartPtr in principle.

The only reason is historical. I wrote it when I wrote assert.hpp. It could
go into Config, if John wants to maintain it (which shouldn't be hard as it
doesn't change much and the changes are generally trivial.)

Maybe. This was once the case. The problem is ensuring that it stays that
way. Every utility component gets put into Utility because, well, where
else? And so it grows (as does the list of maintainers that need access to
it, which was another problem I was trying to address).
