Right now the netlify-toml redirects generated by the serverless plugin point to /.netlify/functions/ and the new persistence feature uses /.netlify/builders/ so we’ll need to expose an API for that.

• redirects: "netlify-toml-builders"
• redirects: "netlify-toml-functions" (alias for default netlify-toml)
