I generally tried to preserve the behavior of consumers where they treated an exception from getInterface(Ci.nsIContentFrameMessageManager) as a signal to use some sort of fallback. I did change the behavior of consumers that walked up to the root same-type docshell before getting the message manager to just get it directly from the docshell they have. Please review those parts carefully, and let me know if you want me to ask some subject area experts to review those.
