Personally I hear GoDaddy and run very quickly in the opposite direction.
Apart from my personal opinion though, I don't think this is likely to be high on the registrar integrations list, there are several others that are more frequently requested that would probably be more likely to be built and maintained than this one.
The beauty of open source is that anyone is free to contribute though, maybe you can find an interested developer or you could also try reaching out to 123-reg team.
