This should be a when, since it doesn't appear to have an else clause

If you're building a project which may be delivered as an executable jar file, it's obvious that parameters can (and should) be supplied as environment variables. However, if you're delivering a project as a war file to be run within a servlet container, this isn't really possible as the war file may be deployed into an already running servlet engine whose environment variables one cannot readily alter.
While I agree that passing parameters as
context-paramsin theweb.xmlfile violates the principles of the 12 factor app, it is a well established mechanism for specifying parameters within the context of a web-app packaged as a war.This patch provides a mechanism for specifying context parameters in the
:ringmap of theproject.cljfile. A key:context-paramsmay be specified in this map; if it is specified, and its value is a map, then acontext-paramelement will be generated in the generatedweb.xmlfile for each key/value pair in that map.
