In the RFC T175146 regarding movin runJobs.php and runSingleJob.php into the mediawiki-core it was decided that runSingleJob.php has to become a Special page and live under Special:RunSingleJob.php. That has been implemented, however JobQueue ChangeProp has not been switched to use the special page. It has to be done eventually.

|Resolved||Tgr||T182475 Handling of structured data input in MediaWiki APIs|
This is effectively blocked by T182475: Handling of structured data input in MediaWiki APIs, since we need Special:RunSignleJob to be able to read structured data (which is currently not possible). Gerrit 388486 puts forward the idea of handling application/json generally for all MW requests.
