> The legacy variants of ManagementXml and AuditLogXml are getting loaded but aren't used, which is a waste of boot time and of metaspace.
> It turns out that the idiom of having the impls extend an abstract base class and then having a static factory method in the abstract class results in all the different impl classes being loaded into memory. Simply changing the abstract base class to an interface eliminates the problem.
> While I'm at it, the legacy impls still have code for the writeXXX methods, which should never be called. So I'll clean that out and replace with a default impl that throws UnsupportedOperationException.
> I'll do some other code cleanup on these too, removing unused params, etc.
