From my testing, the existing idFWD_KWREST sections for `...` without leading arguments are already broken. Defining `RUBY3_KEYWORDS` in parse.y results in broken code such as args being dropped and `no implicit conversion of nil into Hash (TypeError)` when using super. So I don't think there is a point trying to get idFWD_KWREST sections working for leading arguments currently. We are not going to want to switch to idFWD_KWREST sections until we drop `ruby2_keywords` support, as `ruby2_keywords` is significantly faster.
I updated the commit to add ripper support, and added a pull request for it: https://github.com/ruby/ruby/pull/3190

Feature #16378: Support leading arguments together with ...
https://bugs.ruby-lang.org/issues/16378#change-86001
* Author: Eregon (Benoit Daloze)
* Status: Open
* Priority: Normal
* Assignee: matz (Yukihiro Matsumoto)
* Target version: 3.0
----------------------------------------
I think this is very important, otherwise `...` can be used only very rarely.
For instance, `method_missing` typically want to access the method name like:
```ruby
def method_missing(name, ...)
if name.to_s.end_with?('?')
self[name]
else
fallback(name, ...)
end
end
```
See the original feature: https://bugs.ruby-lang.org/issues/16253#note-19.
I think most people expect `def method_missing(name, ...)` to work.
