I’m not sure about you, but I consider JavaScript running in my browser not being able to write arbitrary text to files to be a good thing.

I can already write to file with 'window.(something).createObjectURL' ... which queries user. I simply suggest that 'future javascript' open() (or whatever) supports that with no-more-code needed.
