Ah, but you refuse to actually debate!  As usual, you just repeat your
position as if that were an argument for it.  It is very useful to have
add-ons Implies files affect the main sysdeps list.  Take for example
libc/sysdeps/pthread, where aio is implemented in terms of pthreads.  The
linuxthreads add-on has an Implies file containing "pthread", so using the
add-on enables the sysdeps/pthread code in libc.  A different add-on might
provide a different pthread implementation, but use an Implies file to
enable that same code.
