To be fair, supporting tree-sitter seems really nice.
Perhaps it does not need native support but can be implemented
as a plugin, using Vim text properties?

I have not tried tree-sitter yet, but I glanced at at:
https://tree-sitter.github.io/tree-sitter/
https://github.com/nvim-treesitter/nvim-treesitter

It could provide syntax highlighting for several languages,
based on a real parser of each language. In contrast, vim
native syntax highlighting is based on heuristics with regexps.
Vim syntax highlighting works quite well in general despite using
heuristics, but some complex languages are impossible to get
100% right with vim syntax highlighting (e.g. sh, Perl, c++,...).
It's a bit similar to heuristic indexing (ctags, cscope) vs indexing
with clangd, rtags (etc) which have a full parser and are thus 100%
reliable in principle.

Syntax highlighting with tree-sitter may not only be more accurate,
but perhaps faster and we piggy-back on another tool to support
languages.
