Stepping back for a moment, I think we both (certainly I have) may
have read a stronger claim into your e-mails then you intended to
make. In particular, I think I may well have seen red at the words
"breaking change" in regards to changing libraries, because we came
within a thin margin of throwing boost out of an open source project I
work on about a month ago.
Boost can be quite hard to use in open source projects, where a user
might have some version of boost installed by their packaging manager
(which might be yum, apt-get, macport, cygwin,etc), and not want to go
and have to install another version manually if it can be avoided.
However, the issue of if any changes are made gradually, or in one
break, is different from what kind of include names are used. It is
unfortunate that it is perhaps not advisable to use both at once, as
one of the major arguments in favour of all.hpp is that the
alternative breaks tab completion.
I do hope, modulo phasing in over a number of versions to minimising
breaking, that one standard can be agreed on. In general I prefer one
standard over several!
