I more or less do this, though I started doing it before I knew there was a name for it. (I also write out of order, for the record, and I handwrite the zero draft stage; I find it helps shut my inner editor up, which is worth some deciphering-of-handwriting later on.)
For my comic's scripts, I usually just start brainstorming -- this is what I want the scene to look like and do, maybe so-and-so says this, oh and then so-and-so would say that -- basically it meanders between brainstorming and straight dialogue. Eventually I get the scene mostly down and start transcribing it into actual scripts, cleaning everything up as I go. Short stories -- the few I've done -- I've written similarly, and with modest success.
Novel-wise, this same method got me through two NaNoWriMo wins, but the novel itself (the same one for both) didn't turn out so well in the end. The biggest benefit of zero drafting is it lets me meander, poking and prodding at characters and events and finding out which are dry bones on the page and which tasty meat -- something more traditional outlining methods always failed me at, often drastically. And the biggest
problem with zero drafting is... it lets me meander. It encourages my tendency to throw in the kitchen sink, diving deeply into subplots and sub-subplots and "but what if [secondary character who doesn't need their own arc] did [thing that will eat up ten thousand words]" until I've obscured the shape of the story. My assumption that I'd be able to find it with vigorous pruning has not, alas, held up under revisions.
(Spending over a decade writing a soap opera webcomic where meandering and the kitchen sink were, if anything, welcomed by the readership hasn't helped....)
However, while flawed, the zero draft method has still gotten me much closer to telling the actual stories that are in my head than anything else. I'm currently experimenting with expanding my latest short story, accordion-style, to see if working a zero draft in stages and layers helps. I'll let you know in a year or two how it went.
