Stopping working
The Sonos stuff will not stop working, just your setup will no longer get updates after mid-May. Fine as a whole if you do not use streamed music services. PITA if you do and one of those services changes their code (even if for good reasons) and you need an update to your system. Also will be a PITA if you want to expand your setup as anything new may not work with your existing solution.
