It sounds to me like they're actually trying to do a thorough job of decontaminating the fuel system and making sure there are no lingering issues (or any serious ones from injecting imcombustable material into a high compression engine), rather than shortcutting it and hoping for the best.

And yea it's somewhat labor intensive. That said, unbolting the mounts and jacking the engine up a bit isn't super difficult or time consuming it you have ready access to lifts and jacks in a shop with all your tools sitting within arms reach. Sure fiddling around with extensions to get the spark plugs out might make more sense in your driveway, but if you have the equipment that may change.
