[question] Using lazy files in browser in main thread but in async mode

The docs mention that browsers disallow synchronous XHR and thus lazy files are supported only in Web Worker mode. But binary XHR are supported in async mode, aren't they? When using MODULARIZE'd modules, we're in async mode anyway (and maybe ASYNCIFY could help to yield execution while file is loading over the internet)

(For me, it's mostly a question about consistency/ease of debugging, since in practice the heavy code should be running in Web Worker anyway)

Start with the documentation that limits lazy files to Web Worker mode, then read the MODULARIZE and ASYNCIFY guidance referenced by the issue. Determine whether asynchronous binary XHR can support lazy files on the main thread, and define whether the result should be an implementation change, documentation clarification, or both.
