Change 341133 had a related patch set uploaded (by mainframe98):
[mediawiki/extensions/Nuke] add an API module for Nuke

https://gerrit.wikimedia.org/r/341133

@Anomie raised a valid concern related to this issue: Do we really need an API for Nuke? If I take this script for example, it utilizes existing API modules to emulate the nuke functionality, with the only drawback being that it has to delete each page individually.

Change 341133 abandoned by Mainframe98:
add an API module for Nuke

Reason:
See last comment of Anomie, an action=massdelete would be better.

I clarified the summary that people just want an API to mass delete pages, not necessarily the full equivalent of Special:Nuke. I wonder if we could have action=delete take a generator?

That is a possibility.

I am loading a large number of elements in a local Wikibase installation and I often need to reprocess the dataset.
A batch delete function to mass delete elements inserted by a bot user would be useful.

I’m in the same situation. Deleting a thousand items individually is slow.

Added Wikibase tags which was requested by Lydia.
