I think that the File Writer should trigger downloads on an API call since that doesn't introduce security issues that aren't already there. I'll make a proposal for that.

Well, that gives you a button that does nothing. It's better in the same sense that if you want to get to the moon, a car is better than a kick scooter.

You can already redirect to malicious.exe. You can also already build directly in script and prompt for download (like does). A saveAs() method that works through the download UI changes nothing security-wise, unless I'm missing something.

I'm going to flag the entry point issue in the draft, and DAP has decided to release a FPWD of it (because most of it is still very useful to look at separately from this issue).
