Why? The serialization library was explicitly developed to allow this
possibility for compilers that are not supported by the current Spirit release.
Spirit 1.6 itself is still being more or less maintained just for this purpose.

With Boost.Build v1 the serialization library was set up to either allow in
place replacement of the Spirit subtree or to detect an external installation of
 Spirit 1.6 by means of an environment variable. That's how tests for the
Borland compilers have been run since Spirit 1.8 was integrated into Boost.

I feel that if a library author is willing to devote effort to backward
compatibility he should rather be encouraged than hampered.
