-Taken together, the dependencies across all prioritized elements in a connection
-form a dependency tree. An element can depend on another element or on the root
-of the tree. A reference to an element which is no longer in the tree is treated
-as a reference to the root of the tree. The structure of the dependency tree
-changes as PRIORITY frames modify the dependency links between prioritized
-elements.
-
-Due to reordering between streams, an element can also be prioritized which is
-not yet in the tree. Such elements are added to the tree with the requested
-priority.
+In HTTP/3, stream dependencies that were implicitly encoded by dependencies in
+HTTP/2 are explicitly encoded with strict prioritization.  This simplifies
+priority tree management, eliminates potential new race conditions introduced
+by HTTP/3's multiple streams, and improves framing efficiency with more than
+64 requests.

The can sentence can be removed: it's an editorial.
