I just completed an evaluation of what is contained in Incubator. Here are some details:

• There were 1,020 tests with at least one apparently valid page of content.
• Of those, just under half were "substantial". I define "substantial" as follows: (a) at least one page added to the project in 2017 or later, excluding clear housekeeping additions, and/or (b) at least 25 mainspace pages in the test. 
• Two of those are tests that have been approved and are awaiting creation (Ingush Wikipedia, Elefen Wikipedia). (MF-Warburg: I know these have been slowed down with the developers. Do you have any timeframe on them?)
• Aside from those two, thirteen others have sufficient activity to meet the activity requirement for approval (at least three current consecutive months of at least three registered users having at least ten edits each).
• Of those thirteen:
  • One has been tentatively approved, but is still pending language verification (Gorontalo Wikipedia). (MF-Warburg and Amir: Do we need to look for different experts?)
    
  • One more is now ready for evaluation by LangCom (Shan Wikipedia).
  • One is currently being discussed by LangCom (Pashto Wikivoyage).
  • The other ten are not ready for an approval discussion, for other reasons:
    • Nyungar Wikipedia: Current LangCom discussion on language of content.
    • Sakizaya Wikipedia: There is currently an issue with the language code. The code the community uses, ais, is not an invalid one for the language, at least for the purpose of running a test on Incubator. But the issue needs to be resolved more completely before LangCom fully considers approval of the project. The community expects to try to resolve that in next year's batch of requests at SIL. If anyone wants more information, just let me know. (The test is also still a little stubby.)
    • The remaining eight tests are either too stubby, or their interface translation is incomplete, or both. I am trying to encourage these communities to start filling out pages more fully, rather than creating more stubs.

Any questions, please let me know.
