Yeah, Sitecore added support to other combined roles than stand alone. My worries are not valid any more. Please look at my edit on November 22nd.
My client licence is XP3 (3+3). We allow to have 3 production servers. It looks like for the moment (or not) the only supported role combination is XP0 (standalone) – which is recommended only for local development and testing. Here is a link to Sitecore documentation.
If you planning a fully featured Sitecore Experience Platform installation you need separated server roles: Content Delivery, Content Management, Processing, xConnect Collection, xConnect Collection Search, xDB Reference Data, xDB Automation Operations, xDB Automation Reporting. Is my old Sitecore licence good enough? I has been told on Sitecore slack by Sitecore employee : ” From a licensing perspective, you probably want to look at transitioning to the subscription licensing model by speaking with your local sales contact.”
I will you keep posted.

Based on Webinar – Sitecore Pricing Overview for Partners I can tell that all xDB processing server are PRODUCTION now.
It looks like it was a false alarm. Sitecore yesterday added new combined roles
