There’s an updated (April 2025) Downgrade Rights licensing guidance document from Microsoft. There aren’t major changes, it’s really just updated for the latest product versions – SharePoint Server 2019 is changed to Subscription Edition, for example.

Microsoft announce the general availability of the next on-premises version of SharePoint Server – the Subscription Edition.
Customers with active SA are entitled to use this edition and will need to maintain the SA to keep using it; if the SA lapses then the customer retains rights to SharePoint Server 2019.
There’s no change to the Server/CAL licensing model or pricing, or existing CAL equivalence rights, but note that there is no longer the option to purchase just a licence for this product.
Project Server Subscription Edition is a part of the SharePoint Server Subscription Edition installation and thus also available.

The SharePoint Server licensing page is updated for the 2019 version. And there’s good news – no changes to the licensing from the 2016 version.
