what friction? the DNS RFC has been around since 1987, its not some arcane rune stone of indecipherable glyphs. hell, you managed to get it to work in your panel.
I know nothing about this proposed solution beyond what the summary provided, and I share your anti-GoDaddy feeling in general.
There is, however, a problem that needs to be solved when transferring domains from one registrar to another. I've dealt with many different registrars over the years, and none of them do this the exact same way. Sometimes they don't support authorization codes, other times the destination can't process the codes properly, and the transfer request times out at the source. I'd love to see a better, more uniform and accepted way to handle this process...this may or may not be just that.
