labswiki and labtestwiki are copies of Wikitech, which is maintained and dumped in a special fashion. You can find those dumps here: https://dumps.wikimedia.org/other/wikitech/dumps/
uk.wikiversity.org does not exist.
ecwikimedia, as you rightly note, is private.
The remaining wikis have all been deleted. We dump closed wikis but we do not dump deleted ones.

I hope this addresses your concerns.

Hi!

I am currently working on a dump search and download tool for all Wikimedia wikis. In order to find out which Wikimedia wikis exist I used Wikidata. While comparing the list of wikis from Wikidata with the list of dumped projects I found out that the following wikis are currently not being dumped:
  • alswikibooks (last dump 20180101)
  • alswikiquote (last dump 20180101)
  • alswiktionary  (last dump 20180101)
  • ecwikimedia (never dumped, private but not marked private in Wikidata?)
  • fixcopyrightwiki (last dump 20200220)
  • labswiki (never dumped?)
  • labtestwiki (never dumped?)
  • mowiki (last dump 20180101)
  • mowiktionary (last dump 20180101)
  • ru_sibwiki (last dump 20071011)
  • ukwikiversity (never dumped?)
Is there an uptodate machine-readable list of currently dumped wikis besides https://dumps.wikimedia.org/backup-index.html?

(Off-topic) Spoiler for dump searching tool on my laptop:
$ target/release/wdgrep "asdfdefased" /c/Users/xyz/wpdumps/dewiki-20200701-pages-articles-multistream.xml -v --ns 0
Searched 21437.064 MiB in 8.467969 seconds (2531.5474 MiB/s).

Best regards,
