It is true that, after the modularization, all header files will be found
in the appropriate library's folder. However, it will allways be possible
for a library to provide header files "as if" they were directly in boost/.

After the modularization, it will be possible in princible that two modules
both provide a file with the same name, which may lead to unexpected
results. Currently this is technically impossible.

AFAICT, the change will not affect any other libraries since only
