This has deprecated `nvim-treesitter` setup. It has *not* been removed
yet.
I intend to tag the previous commit to this as `0.1.0` and then fully
remove `nvim-treesitter` setup support in `1.0.0` -- a breaking change.
TODO: We *must* have a way of detaching the plugin for a given buffer or even globally. Currently the plugin does not have it's own capabilities to do so.
