The forcerecursivelinkupdate parameter is not reflected in the API response for the Purge module.

It is also (to me) unclear whether it actually triggers a cascading link table update since the job queue remains largely unchanged (even for high use templates).

To reproduce:
0) Log-in

1. go to https://commons.wikimedia.org/w/api.php?action=purge&format=json&forcelinkupdate=&forcerecursivelinkupdate=&titles=Template%3AWLPA-se (Low use template)

Returned: {"purge":[{"ns":10,"title":"Template:WLPA-se","purged":"","linkupdate":""}]}
Expected: {"purge":[{"ns":10,"title":"Template:WLPA-se","purged":"","linkupdate":"","recursivelinkupdate":""}]}
