Fate of Genesis bus

Hi all,
according to the Genesis launch press kit, the spacecraft bus was to be
ditched in the Pacific Ocean after releasing the capsule. However, I
have seen studies indicating that it could be diverted and its
scientific instruments (two particle monitors) re-used in an extended
mission either at L1, or switching between L1 and L2 or in heliocentric
orbit.
The Genesis landing press kit does not mention the ditching, an article
in AWST hints that the bus was to be diverted and I find that it is
still listed in the JPL's Ephemeris Generator. Does anybody know what
was its fate?
