• Should the other two openapi files be kept in sync with this one?
• Add a line to the changelog? We should say these fields are deprecated and are being removed from the spec.

@daniel-jones-dev makes sense! I've made these changes in my most recent commit.

Thanks.
I also included the additional info about cost control in character_limit description, for the other two openapi files.
Couple nits about the changelog:

• when you add a heading in the changelog file, there is an additional footnote-link that has to be added too.
• Also when you bump the version, you need to bump the versions in the openapi files too.
• Lastly, you can use a changelog section "Unreleased" until we're ready to bump the version.

I guess these steps need to be documented 🤔 I've modified your changes for the above.
