Wikiversity Sinhala:  No content was ever created. Rejecting as stale.

Wikiversity Tamil:  The requester hasn't been active on meta since 2013, but is occasionally active at Tamil Wikipedia. I will ask if he plans to do anything with this. There was one page (effectively, a main page) created two years earlier than this request, but nothing has been done since. Unless creator tells me otherwise, I intend to reject as stale.

Wikiversity Zazaki (diq): I suppose it's a fair question to ask why diq is able to co-opt the name Zazaki, which more correctly applies to the macrolanguage as a whole (at least according to ISO 639-3). The Wikipedia in this language calls itself Zazaki (or Zaza), too. ISO, on the other hand, uses "Dimli" for langcode diq. Still, there are 94 pages in this test, so it is eligible. You can tell me at a future date if you want to try to change the working name the projects use.
