Also, messages should not be changed and reused - that results in showing wrong messages such as

$1 transclusions
$1 links

etc...

@Ajayrahul We've a little issue reverting the localisation of your code: your repurposed messages to give them a new meaning.

This choice makes it's not straighforward to revert: we need to track on TranslateWiki translations update, revert them, prepare a change.

When you change the meaning of an element interface, please create a new message instead of amend existing ones.

The translation commit above was meant to be picked up by daily LocalisationUpdate run, but that did not happen for some reason.

Does that mean it will take another 24 hours before we get the WhatLinksHere filter links back on our language version unless we fix it locally?

Hopefully sooner than that, T135849 was filed to investigate.
