However, they are innundated with the basic repair and maintenance of the RMN and GSN fleets given the removal of the the 4 main repair facilities at Manticore and Blackbird.
Remember, the conversation in SVW was whether it would be more expedient to send the Nike back to Manticore where the SUPERIOR facilities could repair the ship quicker, or make the repair at Hancock. Manticore's facilities were used more for heavy updates and scheduled maintenance cycles (Like Carrier SLEP), and the repair yards were used for the lower level stuff.
The difference is probably Manticore/Grayson yards being similar to a car manufacturer's Dealership's repair shop, while the repair yard are closer to your neighborhood muffler shop. The neighborhood repair shop can probably fix it, but thy might not have the latest parts/tools/knowledge to do the job, and it will take longer to complete. (While a repair ship is more like the quick-change oil shop down the street - it will change the fluids and slap come tape/sealant on the holes, so you can limp back to the repair yards.
However Hancock Station could do this major replacement quickly enough that it was not worth expending the travel time for a round trip. Which means your analogy undervalues the repair yards. I expect that throughout the war the repair yards were more likely used for the scheduled maintenance cycles, leaving the major space stations to handle construction and heavy updates.
