Not for the airline. The short hops aid aircraft utilisation, in-between longer haul flights.

Also, a RUH resident can travel all the way to GVA on the GC. RUH was not chosen randomly. A lot of cash-rich residents there with not-so-great / mixed bag commercial options.

Same logic applied to KWI in the beginning, but haven’t been in yonks and not sure if the GC is still deployed there.
