Summing up my observations here so they don't get lost:

Neovim only depends externally on treesitter parsers, but it bundles its own specific queries, mostly synched up verbatim from the nvim-treesitter project. So it seems packaging upstream parsers and their generic queries isn't enough, since then we end up still dependent on nvim-specific queries, plus making sure our ts parsers don't break those queries and similar headaches that the nvim-treesitter project aimed to handle before being archived.

removed the queries symlink, as the queries nvim vendors are actually different.
