I disagree. If you mark Query as subject to change, in fact the whole
package as subject to change, I would be quite happy to migrate EOB as
often as was needed.
I have no need of Query, so we could merely clone CompMgr into
ServiceMgr as Stephen says (so we can use it immediately) then negotiate
changes to it.
