In general, I agree, but there's a problem: any method on the wrapper
could collide with an index or metadata item and thus get indexed in the
catalog. Thus, the method is "private" in the sense that it's not to be
considered part of the "wrapped" object.
It may not seem very likely that someone has an index called
getWrappedObject, but there's (stupid) support in Archetypes to create
indexes from fields based on the accessors of those fields, so an
auto-created index for an AT field wrappedObject would default to being
called getWrappedObject(). Again, not hugely likely, but I think it
makes sense to say that all methods on the wrapper that are *not*
"indexable" are "private" in this sense.
