FYI if Hubble had gone to single-gyro mode circa 2014-17, the Arrokoth flyby would not have happened. HST isn't very useful for the ecliptic with a single gyro, and no other telescope could provide the required astrometry.
That was quite possible, and was acknowledged as a significant technical risk in the Kuiper Belt Extended Mission (KEM) proposal. But we were lucky.
