Using messaging Center with "sender" type as message content.

We have been using the messaging center by having the "sender" represent the content of the message, rather than the actual "sending" class.

For instance:
MessagingCenter.Send(new AnalyticsTrackedMessage(pageModel, actionName), string.Empty);

Will this get us into trouble (as far as how MessagingCenter tracks references, etc?)

We were trying to avoid having subscribers have knowledge of "who" sent a message (and we wanted to publish the same message from multiple locations in a few cases.)

Should we be using TinyMessenger instead to get these semantics ?

Thanks for any insights -
