I've interpreted the warning as Cisco removing their support and liability requirements for the optics themselves, "My SFP doesn't work, help". I wouldn't expect any data issues whatsoever. They'll continue to support the switch as normal for non-gbic issues. I've been running service unsupported-transceiver for many years with no issues. As long as it's [eventually] recognized, it's good.
