I don't consider all modifications equally disqualifying. Adding

    project : requirements <library>/boost/headers ;

to all test Jamfiles is indeed a global change, but it's mechanistic and 
does not require any further maintenance, so it's not going to be a burden 
for the maintainer of the library.

Adding a build/Jamfile with the dependencies, on the other hand, both 
requires getting the dependencies correct and keeping them correct, so it 
does impose an additional responsibility on the maintainer. (It also may 
have packaging implications downstream... and if we don't magically solve 
cycles, those are going to be a problem too.)

The idea of being "incremental" is to allow those maintainers who would like 
to accept the additional responsibility to be able to do so, and to allow 
those who would rather not, to, well, not. This is not invalidated by our 
adding a line to their Jamfiles - once, without them needing to do anything 
about it.
