Textbundle support

[leowill01]

I'm new to learning about Quarto but I'm a huge fan of R Markdown. I'm wondering if Quarto will somehow support a Textbundle-like format in the future. I think this would be great because it would solve many problems of portability when it comes to markdown-based documents.

I don't see how this would affect usability of e.g. the source RMD (.quarto?) file as programs could just find this file in the *.textbundle. And if Quarto scripts output other data I imagine it would function the same as if it was just running from a non-bundled script where you have already programmatically specified where output would go.

Is there any kind of movement to shift towards self-contained source+assets bundle filetypes?
