Isn't a more fundamental reason to not use fi is that it's not a real phone network ? Nobody other than google can operate a client as intended on the fi network. The network switching stuff isn't a standard or open source AFAIK. It's not a part of AOSP. Only google's licensed devices get that logic as a part of google play services. All other devices will operate in degraded mode where you are basically using a single carrier just like other carriers. So why bother ?
