Question: Should we allow duplicate keys in our JSON objects ?

I was attempting to add the official pre-commit hook `check-json`

https://github.com/pre-commit/pre-commit-hooks?tab=readme-ov-file#check-json

And when testing the hook locally it showed two JSON files that had duplicate keys.

Should we standardize all our JSON files and enable checking or continue with the current inconsistent approach ?

So it just shows two but there are many in the "GR" file

There is a discussion below about this:

Start with the proposed pre-commit check-json hook and the JSON files it reported, including the mentioned "GR" file, then review open PR #12245. Done means the project has a decided duplicate-key policy, affected JSON files follow it, and the check passes consistently.
