"Legacy-ish" note in the header of the README is confusing.

[im7mortal]

The first thing we see on the library is that it is labeled "Legacy-ish". It has been exactly( :smile: just noticed) 3 years since this label was placed, and the StreamSaver.js is still more than relevant.

I am still confused about where the File System API ends and the File System Access API begins. Firefox and Safari in the foreseeable future for security reasons will not implement methods as showSaveFilePicker .

In my opinion, it would be worth removing the "Legacy-ish" note. It causes a lot of confusion.
