+  # for replacing this derivation:
+  # option 1:
+  # - the above pr is merged
+  # - new taplo version is released https://github.com/tamasfe/taplo/pull/502 (with my change)
+  # - nixpkgs-unstable gets the updated version
+  # - we update to nixpkgs-unstable that contains the updated taplo version
+  # option 2:
+  # - given that taplo currently consumes >1 mb of memory, it'd be nice to have
+  #   a custom bin that wraps taplo-lsp crate that *only* provides lsp for .replit
+  #   files. this should reduce the amount of consumed memory by a good amount.
