> dart on the server is not officially supported
What gives you that idea? The Dart VM is listed on the platform page for command line and server side programs. https://www.dartlang.org/guides/platforms

The focus of Dart 2 and beyond is the client side [0].
You can definitely run Dart in the VM, but beyond the HttpServer API, server-side support is mostly a community effort.
My point isn't that this is a bad thing, it's that it makes sense for Firebase to be promoted because Dart doesn't have _official_ server-side support.

I do agree they have pivoted to a more client-sided branding though.
Analogy: JavaScript is focused on the client too, but people also use it on the server.
