I understand this. But I've named 12 libraries.
database/postgres/library/c++/libpqxx
library/c++/glibmm
library/c++/libxml++
library/c++/net6
library/c++/obby
library/c++/sigcpp
library/c++/stdcxx
library/desktop/c++/cairomm
library/desktop/c++/gtkmm
library/desktop/c++/mm-common
library/desktop/c++/pangomm
library/desktop/c++/gtkmm

Which should we preserve?  How do you suggest to do it in non-full-hack 
way? If we deliver g++ libraries in /usr/lib, they will be seen first.
So, at least you'll have to set LD_LIBRARY_PATH for affected software.

I don't see any sense in preserving desktop libraries. I've looked at 
firefox / flash player / openoffice. They don't need these libs.
The only libs which could be worth preserving for compatibility IMO are

library/c++/libxml++
library/c++/sigcpp
library/c++/stdcxx

What essential software does depend on mentioned libraries?

Again, if you need them, you can always copy them manually from older 
distribution to /usr/CC/lib, set LD_LIBRARY_PATH and try to run that 
software.
