Snidely noted that:

I imagine that the ground folk are making sure there's space for the
pump in the down manifest. That's one of the reasons it was put in storage,
I believe. (External storage, that is.)


Seems I misread or misguessed on that. Froma NASA Spaceflight News:

Leaving the failed PM on the POA long-term is not desired since
engineers believe the failed PM could be re-used in the future, since
only one small component inside it (the FCV – Flow Control Valve) is
failed, and thus an external FCV could be fabricated in the future, and
connected to the PM in order to return it to service.

Maybe C282Y is simply one of the hangers-on, a groupie following a
future guitar god of the human genome: an allele with undiscovered
virtuosity, currently soloing in obscurity in Mom's garage.
