Must I translate the internal links «Special:X/Y|X»?
Oh, I was desperate to check the change hehe, excuse me! Yes, not it is fine and it doesn't detect as fail the correct format. I already translated all the SMW's strings, so tomorrow I will try to begin to review all the Spanish translation, because I have detected errors that have to be fixed, some of them are not very alarming, but there are another that have to be fixed until of the release of SMW 3.0. I am expecting the release, I want to do the best as possible, and what I can, to collaborate and improve SMW :).
What just comes to my mind: Never ever change the link [[Special:Types/Date|type]] to [[Especial:Tipos/Fecha|tipo]] because in this case everything breaks for people that use Spanish on a non Spanish wiki. You can only do [[Special:Types/Date|tipo]]. I think that adding an alternate label was possible before so disabling the link check was a pretty bad idea since it will do more harm than good.
Oh, true... Excuse me, Karsten. I will fix it in TranslateWiki. I will notice you. I am busy now, but I will do it and the Twitter issues soon.

Well I did not think of this either. No big deal but the links should remain canonical. I could have figured this out earlier, too. Still I understand why you originally asked for this. (related discussion for further reference)
