Unfortunately I feel the same.

By doing this split aren't you making an intrusive container and then 
layering the resource management ontop of it exactly as I suggested?

Isn't this the same thing?

Right if you have a non-intrusive container and access to the source 
code you can, most likely, refactor it to be an intrusive container but 
I don't see how that is comparable to being able to layer an 
non-intrusive interface over top an intrusive container without changing 
the implementation.

To put it another way if there was only intrusive_trie in boost. And a 
boost user using boost burned to a cd (read-only) she should be able to 
make trie in user code by writing a simple non-intrusive adapter.

If there was only trie in boost in the same scenario she would not be 
able to make use of boost trie to implement intrusive_trie in user code 
short of copy-paste-modify.
