Here's a copy of the commit message which should explain things...

   message.c: Add option to suppress the Message channel AMI and ARI events

    In order to reduce the amount of AMI and ARI events generated,
    the global "Message/ast_msg_queue" channel can be set to suppress
    it's normal channel housekeeping events such as "Newexten",
    "VarSet", etc. This can greatly reduce load on the manager
    and ARI applications when the Digium Phone Module for Asterisk
    is in use.  To enable, set "hide_messaging_ami_events" in
    asterisk.conf to "yes"  In Asterisk versions <18, the default
    is "no" preserving existing behavior.  Beginning with
    Asterisk 18, the option will default to "yes".

    NOTE:  This change does not affect UserEvents or the ARI
    TextMessageReceived events.

    * Added the "hide_messaging_ami_events" option to asterisk.conf.

    * Changed message.c to set the AST_CHAN_TP_INTERNAL property on
      the "Message/ast_msg_queue" channel if the option is set in
      asterisk.conf.  This suppresses the reporting of the events.
