There have been some discussions on the proposal - also some mails were sent to this list, but I discarded them as a list admin because they were just copies of people's comments from the Meta page without it being clear who was sending these mails - but nothing convincing was brought forth, it was rather derailed by pointing out "oh but there are so many contributors!!!". I closed the proposal accordingly.

Comment for the record:

This is still, as pointed out on the previous request, "an extinct proto-language". New Wikipedias in ancient or historical languages are not allowed by the Language Proposal Policy, and especially in this case, there is really no point in having a Wikipedia in a language that nobody uses anymore, while at the same time, Wikipedia in the current form of the language is alive and thriving. --MF-W 21:06, 16 May 2021 (UTC)
