We already have a perfectly fine, native development platform in the form of Debian GNU/Hurd. I do not see how creating another GNU/Linux distribution, and putting the label "GNU" on it, should help in developing the Hurd, or getting people excited about it. It would be a huge backwards step actually.
How would GNU differ from a very tweaked GNU/Linux system that behaves like GNU does today? As I noted before, GNU/Linux already provides all the things GNU already has, and includes a couple more that we don't have.
