I am assuming that in 2.4 the notifier send-uuid workaround logic will be removed.
For 2.3 we can introduce a new, global UC property:
_enabled_send_uuid_check = True
This property will control whether the notifier will perform the send-uuid
workaround. If the property if False or absent the notifier will not perform
In 2.4 we can either:
1) Automatically have this property removed when any of the UC clients are run.
2) Have it removed the first time the user manually changes the send-uuid
setting via the send-uuid checkbox on Authority Properties (issue 1730).
It really depends on how aggressive we want to be about turning off the workaround.
