Hello everyone,
We are planning to rework ILocalizedException, which will break anything implementing the interface. Ticket: T287405 https://phabricator.wikimedia.org/T287405
TL;DR: The change will deprecate ILocalizedException::getMessageObject() and replace it with ::getMessageValue()
Of course, we will take care of updating affected Wikimedia deployed extensions.
Please refer to the ticket and comment if you have any questions or concerns.
Best,
