There really isn't much point porting the Dev preview as there are still quite a few quirks that would probably just become worse with a port. I can't see a developer wanting to spend time porting a rom that really isn't meant as a daily driver even on the devices it's designed for. It would be tough to figure out if a bug is caused by code in the preview build itself, or the ported code.
Unfortunately, you'll probably have to wait until the final release of L for developers to port it (and even then it may take time to iron out the bugs)
