+Naming
+------
+
+For symbol names and documentation, new usage of
+'master / slave' (or 'slave' independent of 'master') and 'blacklist /
+whitelist' is not allowed.
+
+Recommended replacements for 'master / slave' are:
+ '{primary,main} / {secondary,replica,subordinate}'
+ '{initiator,requester} / {target,responder}'
+ '{controller,host} / {device,worker,proxy}'
+ 'leader / follower'
+ 'director / performer'
+
+Recommended replacements for 'blacklist/whitelist' are:
+ 'denylist / allowlist'
+ 'blocklist / passlist'
+
+Exceptions for introducing new usage is to maintain compatibility
+with an existing (as of 2020) hardware or protocol
+specification that mandates those terms.
