Currently, it is possible to set a data-uri as the root url (in a correct format https://en.wikipedia.org/wiki/Data_URI_scheme) I think that's one way you could handle this situation.

Or one could fork the code and change a couple of lines to make this work, technically it would be just a couple of lines of code, but I think policy-wise it needs to be thought out.

Please follow the project and feel free to start an issue thread, we can discuss further! :)
