The NOCC project should support %1$s as insertable parameters
This is about MediaWiki's Translate extension.
The NOCC project uses %1$s as the parameter format. It should be supported as insertables. This is similar to $1 in MediaWiki and other projects, and the configuration is very similar, so marking it as #Easy.
This is almost the same as https://phabricator.wikimedia.org/T150250 .
