Why? one would have on his machine either

a) last boost release version
b) or last boost release version + validated upgrades.

I don't see how this would make anything harder. If for some reason
it does, you can always just skip the upgrade and wait for the next boost
That is, one can be no worse off than he is now.

It seems that this is functionally equivalent to my proposal.

Well, the current situation is a hodgepodge as it will always be. I've
supplied serialization support for standard collections and Matthias
Troyer has enhanced it. I've done it for a couple of types which
I tought were important but it seemed it wasn't getting done any
other way (e.g. shared_ptr) and some which were contributed
(e.g. variant) and some have been done by the respective authors
(e.g. data/time, multi-index). Right now they are in the namespace
of the author - seems kind of arbitrary to me. And some authors
have included serialization headers as part of "convenience headers"
which I'm not crazy about. On the upside, though this "hodgepodge"
lacks a certain aesthetic consistency, it doesn't create many
real problems and trying to get everyone on the same page would
be so hard as to not be worth the trouble.

So, you're agreeing with me? or not?
