When writing https://github.com/wildfly/wildfly/pull/16617#issuecomment-1466887853 I went looking for Admin Guide docs to link to re how the response for an operation that supports wildcard addresses should look, and I didn't find one. I though there was something in https://docs.wildfly.org/27/Admin_Guide.html#format-of-a-detyped-operation-response but I misremembered. (That section would be the logical place for the response documentation, with something added to https://docs.wildfly.org/27/Admin_Guide.html#Global_operations as well where wildcard address support is noted for the specific operations that do support it.
