Had the same question, until I've read your comment

For everyone else with the same thought:

Quick context: Neovim 0.12 (released March 29) ships built-in treesitter support, a native plugin manager, and native LSP completion. The nvim-treesitter maintainer had been rewriting the plugin to require 0.12 - and documented this clearly. Users kept demanding backward compat with 0.11. Maintainer burned out and archived it. The Hacker News thread sided overwhelmingly with the maintainer. Hard to disagree.
