Object key forces underscore / snake case

[nboliver]

Curious what the rationale is behind forcing object language keys to use snake case?

We are mostly using document translation, except in one area where we have a settings document that doesn't need translating, but one of its text fields does.

Gatsby / gatsby-plugin-react-i18next is being used on the front end, and all our language keys are hyphen-separated so that they match up with what we have set in the gatsby-plugin-react-i18next languages array. The values from that array are used to set the html language attribute, where a valid language tag is hyphen-separated

Is there a specific reason to force snake case on object keys?

Actually the function you are referencing is not in use. You can use hyphen separated language codes if you want.
