Not surprising
These aren't technical certifications per se, they're sales and marketing competencies. As in, this partner has been fed enough sales content and has enough experience to effectively sell Technology X. I think they're just not bothering to continue actively supporting non-Azure deployments of various technologies. After all, if a technology is available in Azure as a purchasable service, there's no reason for Microsoft to help channel partners sell it when they can collect the money directly.
The next few years are going to be interesting for Microsoft. It's very obvious that they're done selling one off software licenses by default. They definitely prefer the lock-in of permanent revenue streams renting capacity in Azure. Some companies will never fully migrate to the cloud, but the resistance is getting less and less each year. That's going to mean interesting times for hardware vendors as well, who will end up mostly selling to cloud providers.
