+- fast, accurate and more granular font-locking
+- fast indentation
+- common Emacs functionality like structured navigation, `imenu` (an outline of a source buffer), current form inference (used internally by various Emacs modes and utilities), etc

+Working with TreeSitter is significantly easier than the legacy Emacs APIs for font-locking and
