16.3 - Sending Message Events to Process Models

@stefan Again, that's fine but it assumes nobody has any processes that use that functionality - I'm not sure we can assume that nobody uses the functionality without knowing everything everyone has ever done, which of course we don't know! It seems a little short-sighted to just suddenly deprecate this functionality.

@mschmitt It can result in performance issues, presumably if there are many instances of a specific model (as described here - https://forum.appian.com/suite/help/16.3/Messaging_Best_Practices.html). However, it is often useful to message a process model and "correlate" on a piece of business data rather than the alternative, which is to implement a process report to reterieve the process IDs and subsequently message each of them individually. I have seen this implemented in a number of projects, and I'm assuming that those clients don't wish to rewrite what would effectively constitute the core architecture of the solution.
