I just realized that this has existed in Hive for a couple years now, but the only reference to it that exists on this page in the wiki https://cwiki.apache.org/confluence/display/Hive/LanguageManual+DDL is an offhand remark in the documentation for ALTER VIEW AS SELECT. Looks like it was implemented as a response to HIVE-1078<https://issues.apache.org/jira/browse/HIVE-1078>. It even looks like there's a reminder to update the wiki, but it doesn't seem like the wiki was ever updated.
