It's so glad that Ceilometer is the first consumer of versioned
notifications.  Can I understand it as a trend that versioned notifications
will replace unversioned notifications even though versioned notifications
may have the only consumer for long time?
You know Ceilometer consume unversioned notifications for now. So should we
replace unversioned with versioned one by one according to the link[1]
because we can't consume both as then we'd end up duplicating data? It may
result in data lost with thoroughly transformation.
