Interwiki bot needs an enhancement or an serious upgrade.
I can mass create pages (articles, categories, template) on some small wikipedia. For each page usually i can leave in footer old-style interwiki links to enwiki and/or other wikipedias (e.g. [[en:pagename]])
Now, it's necessary somehow to remove these interwiki links and simultaneously to attach newly created pages to existing wikidata items.
As an alternative, or as aditional feature, interwiki bot must ”be intelligent” and to be able to search on other wikipedias for identical name of page and to make connection between these pages on wikidata (this option is good when page has no one interwiki link).

Version: unspecified
Severity: enhancement
