Not when you start to employ pre-compiled headers.  e.g. with 1.32 we 
were require to include serialization/shared_ptr before shared_ptr.  We 
had shared_ptr in our pre-compiled header which meant we had to have 
serialization/shared_ptr in our pre-comiled header.

But then this required us to put all archive types we may use above the 
serialization headers.  This is undesirable but we have had to do it for 
1.32 because of the shared_ptr problem.

I understand the shared_ptr problem is gone with 1.33, but I'm just 
trying to point out that when you start using things like pre-compiled 
headers and such which are pretty much essential for build times of 
large scale projects rather than just unit tests, then header dependency 
orders can become a big issue and I believe these need addressing.

A library that forces dependency orders on end users is not easy to use 
in large-scle projects IMHO and the issues we are hitting with 
serialization demonstrates that.
