Make ChangeLog Consumer queue/backlog size available via web request

It would be great if the ChangeLog Consumer backlog/queue count was available via a web query like it is on the Daemon Extended Log page. I'm not sure if this could be a SOAP/REST request or just part of the status page dump.

Either, the desired outcome is that external processes can monitor the queue size (without having to create db accounts/permissions/calculations, etc) and doing things with that info, like alerting or programmatically make decisions like when importing 25K records into a group, slowing down or temporarily suspending the process if specific CLC's queue gets too long.
