It’d be nice to have a way to use the FileAttachment helpers with things that are not file attachments. E.g., https://observablehq.com/@mbostock/localfile

Similar suggestion for remote parquet files support in DuckDB:

I'm often something that's based on:

remote = require("@observablehq/stdlib").then((d) => d.FileAttachments(url => url))

(… except it also tries to detect and fix cors issues).
