I'm wondering if they're going to need multiple warhead options, you can only get so far with smart fuzing.
Land Attack - they really need a penetrator warhead to match BROACH on Stormshadow.
Anti-Shipping - blast frag, potentially with the radial shaped charges seen on other SSMs.
SEAD/DEAD - needs to be an area-effect, blast-frag can just about cover it, but cluster weapons probably better
Anti-HVAA - frag, or expanding rod
And while blast-frag can just about cover everything, particular with a precursor warhead, the optimal size of fragments and direction of blast are different for the different roles.
I'm reminded that the French did originally want different warhead options on Apache
