The msvc toolset has the <debug-store> feature with "database" being one of 
the available options (which stores debug info into a program database / pdb 
file). How about streamlining your suggestion with this (or the opposite way 
around)?

With proper toolset(?) support, perhaps using <install-type>DBGSYM with the 
install rule would be sufficient?
