> -entry remains unacknowledged.  If a new header to be inserted into the dynamic
-table would cause the eviction of such an entry, the encoder MUST NOT emit the
-insert instruction until the reference has been processed by the decoder and
-acknowledged.
-
-The encoder can emit a literal representation for the new header in order to
-avoid encoding delays, and MAY insert the header into the table later if
-desired.
-
-To ensure that the blocked eviction case is rare, references to the oldest
-entries in the dynamic table SHOULD be avoided.  When one of the oldest entries
-in the table is still actively used for references, the encoder SHOULD emit an
-Indexed-Duplicate representation instead (see {{indexed-duplicate}}).
+The encoder MUST NOT emit an instruction that evicts an entry while a reference
+to that entry remains unacknowledged. When the encoder encounters a blocked
+eviction in the course of encoding a header block, it SHOULD emit a literal
