OK.
However using a reference to the dummy library does not work because the 
library does not exist, I had only defined the target to propagate the 
includes. So instead of making my project on /user-config//boostheaders, 
I now just added /user-config in the sources and ... it works(see 
example below).
Is this intended ?

And to use this trick for different groups of include libraries, could I 
define multiple projects in my user-config.jam? I guess not but wanted 
to ask to make sure.

<user-config.jam>
import project ;
project.initialize $(__name__) ;
project user-config
: usage-requirements
<include>/path/to/boost
;

# lib boostheaders ;
</user-config.jam>

<in the Jamfile in the root-dir of my projects>
lib mylib_which_includes_boost_headers
: foo.cpp bar.cpp
/user-config
# /user-config//boostheaders
;
</Jamfile>
