1. An intuitive structure - Tree-sitter’s output is a concrete syntax tree; each node in the tree corresponds directly to a terminal or non-terminal symbol in the grammar. So in order to produce an easy-to-analyze tree, there should be a direct correspondence between the symbols in your grammar and the recognizable constructs in the language. This might seem obvious, but it is very different from the way that context-free grammars are often written in contexts like language specifications or Yacc/Bison parsers.

   This is a big issue because each version of a language grammar would need to be converted into tred-sitter form

   
   

   But anyways I don't see the issue with pluralism in the parser generator space, why would one exclude the other?

support LR(1) for example)

Really?  AFAIK it uses a GLR parser and hence handles LR(1) and more.
