I certainly hope the mission goes as planned but it does feel like SLS is the wrong approach in the time of reusable rockets, even if this specific mission profile would probably have demanded the booster be expendable. Using the Shuttle main engines - designed and made to be 'refurbishable' rather than 'reusable' but still dumped into the ocean after each mission - and the SRBs (solid boosters) still gives the impression of the booster design being dictated (at least in part) to accommodate the needs of former Shuttle contractors. If either Starship+Superheavy or some other fully reusable heavy left vehicle comes on-line it will be hard for NASA to justify spending billions of $ on, well, a flying pork barrel. Sure, it has been proven time and time again that canned pigs can in fact fly but that does not make them the go-to transport.
