Hey! Thanks so much for opening this pull request!

Sadly this PR got stale and didn't have any activity for some time. We're trying to do better with PR reviews! To get a better overview of all actionable PRs we're going through all open PRs and triage them. Since we won't be able to do everything and adding new features always means added maintenance burden, we have to be more picky about what's beneficial for the average user and the project itself longterm.

Having said all this, we dropped the ball on this PR and we're sorry about not responding to it earlier. As said above, we want to do better in the future but here we should have communicated earlier what will happen with the PR.

Unfortunately we won't merge this PR at the moment because we need a better, more generalized strategy at providing types for plugin options. Manually typing them for each plugin isn't an option and we should generate them from the pluginOptionsSchema API. But that's not done yet.

We absolutely want to have you as a contributor and are sorry for any inconveniences we caused with replying too late to this PR.

Thanks for submitting to Gatsby! 💜

Sounds like you'll be looking for something like joi-to-typescript to autogenerate the types? Sounds great! Unfortunately, I'm not really working on the project I was using gatsby for anymore, so yeah, replying late means I'm probably not going to hop on that effort any time soon. Good luck with the rest of the typescript migration in #21995! 💛
