I'm not sure what that accomplishes.
The "entire API surface area," as you put it, surely includes more functions than the only one you need for a landing page's hello-world. I don't evaluate something like Simulacra with a hello-world in mind, else I wouldn't need Simulacra.
My advice is to just change "one function" to "tiny API". Or maybe "just three functions in the public API". That's just as respectable and spares you from needing to split your API into a pointless "helpers" namespace.
const {bindObject, bindEvents, animate} = require('simulacra')
^ looks ideal to me.
