No, they haven't been updated to cope with lazy loading (they are defined in a top-level if statement to prevent conflicts in older versions of R).
vcov.coxph is actually vcov.coxph<-function (object, ...) { rval<-object$var dimnames(rval)<-list(names(coef(object)),names(coef(object))) rval } since object$var doesn't have dimnames.
As Torsten has suggested, it looks like they were neither registered nor exported from the survival namespace, but the objects are in the namespace. (Nothing to do with lazy-loading, then.)
True. I misconstrued the advice against top-level code in packages.
