According to [[ https://phabricator.wikimedia.org/diffusion/EWBA/browse/master/docs/change-op-serializations.wiki$43 | the docs ]], "you can either add or remove aliases individually, or send the full set of aliases for a language". But it seems like sending the full set of aliases is not supported if the set is empty?
**Steps to reproduce:**
Make a wbeditentity request with data set to `{"aliases":{"en":[]}}`
**Actual result:**
No changes are made.
**Expected result:**
Existing English aliases are removed.
**Deployment Blocker**
We have to check whether this is to be qualified as a breaking change or not, and follow the proper process accordingly.
**Hints**
Probably a good place to start is: \Wikibase\Repo\ChangeOp\Deserialization\AliasesChangeOpDeserializer::getIndexedAliasesChangeOps
