Another idea is delegating parts of buffer to Elisp/alternative parser.
Tree sitter provides support to documents written using a mixture of
grammars: https://tree-sitter.github.io/tree-sitter/using-parsers#multi-language-documents
Macros can be considered such a "mixed" grammar with macros being a
grammar of their own.
AFAIU, tree sitter allows excluding certain file ranges from parsing
and instead parse the excluded ranges using alternative grammar. If
Elisp can somehow tell tree-sitter backend not skip parsing
macro-looking lines, it should solve the problem at least partially.
