It wouldn't.

My view is that :

if a library can be built and used with visibility=hidden 
there is no reason not to build it this way, this flag should be in the
Jamfile.

If a library cannot be built and used with visibility=hidden
there is no reason to build it this way so if visibility=hidden isn't in the
Jamfile, adding for a tester is a pointless exercise.

Hence, visibility=hidden should be added to the Jamfile if possible
so that the library will be built and tested with visibility=hidden if and
only if
it's supported. There is no scenario under which adding it to project.jam
would be beneficial.
