Ada-mode to be abandoned?

[Philip Kaludercic]

I recently came across this message on the ada-mode-users' mailing list:

  https://lists.nongnu.org/archive/html/ada-mode-users/2023-11/msg00000.html

Stephen (the maintainer, in the CC's) indicates that he would like to
retire from maintenance, which might mean that the package could become
abandon-ware.

One note he makes is that the current implementation could be
simplified, by just using tree-sitter, instead of the approach that
makes use of a custom parser:

--8<---------------cut here---------------start------------->8---
2) Drop the wisitoken parser generator and runtime, use tree-sitter
   instead. This requires writing a wrapper for tree-sitter to match
   the wisitoken syntax-tree API; then the current wisi indentation
   code can be used.

   This maintains all of the ada-mode features, while reducing the
   maintenance burden significantly.

   I believe the tree-sitter error correction is less powerful than
   wisitoken, but it would be interesting to see if that matters in
   practice.
--8<---------------cut here---------------end--------------->8---

What I am wondering, is if this simplification were to take place, if it
would be possible to add ada-mode (or ada-ts-mode in that case) back to
the core?  I would be glad to help out, since I've been interested in
working with Ada for a while but never got it to work, I have just been
struggling with understanding how `treesit-font-lock-rules' is supposed
to be used, so some help would be appreciated.
