I don't feel strongly, but all of the "main bin spec" specific knowledge is centralized here in GetCorefileMainBinaryInfo, and converting the constant values this LC_NOTE uses for binary type into the enumerated values seems best kept local to this area.

Yeah, it's not great - but we're checking them in opposite order in the duplicated blocks, so I could make a lambda that did both, but it would need to take an arg about which to prefer and wouldn't be that much better I think.
