Remember that grafted replacements should have a compatible ABI.

This is the first result I found when searching for "Ruby ABI compatible"

https://www.ruby-lang.org/en/news/2013/12/21/ruby-version-policy-changes-with-2-1-0/

So, if they've kept that policy, this should be fine.

Thanks for taking care of this!
