Maybe we should create a petition to Microsoft to leave older clients without support but working as they used to before Skype migration to cloud? I guess it should be easy for them to do that with minimal resources usage. Somebody trying to login from older client? Connection made as it was before. When trying to login from newer clients - connection via cloud. Maybe these two methods would coexist happily. Just a petition and let know on major Windows Phone forums so that numerous WP < 10 users would join too.
