Speaking for myself, I think DC has worshiped at the altar of continuity for too long, and need to relearn storytelling and engaging characters. So I'm pretty on-board with such a change.
Will DC go looking for writers of Tim or Steph? No.
But I hope that the future DC, after going through these changes, will be much more ready to publish a story of Steph as Batgirl (or Robin!), or Tim as Robin than they are today. The quality of the pitch will be more important than how well it fits into DC's current continuity.
