There's some good feedback in the https://github.com/fermyon/developer/issues queue when it comes to Spin technical docs content. However, a bulk import doesn't make sense since https://github.com/fermyon/developer/issues tracks issues related to the site itself (which hosts documentation for Fermyon products) and other Fermyon products.
This issue can be closed once we've migrated all of the relevant Spin technical docs-related issues from https://github.com/fermyon/developer/issues into this GH repo (and closed the original issues with a pointer to their new home).
