There is no value to these features at this point

hmmm - normally I just respond to bug reports. If there are no users
there would be no such reports so probably nothing would happen.

within the boost serialization library or in other projects?

In any case, I just incorporate an std header if there is one, next I
select a boost header, and finally I write it myself.

I have no idea how frequently the boost serialization library is used.
I'm sort of thinking it's more than 25 times. But I have not statistics
on this. I would love to know this.


The one thing that might happen in the future is that BS depends upon
some other boost library which gets "upgraded" to C++11 so that BS is no
longer compatible with C++03. But this seems unlikely. Boost libraries
don't get much maintenance. Once it works and passes all tests, no one
messes with it. upgrading working code from C++03 to C++11 isn't going
to add any benefit, so there it's more attractive to spend one's efforts
somewhere else.
