That makes sense given the collaborative efforts between USL and Sun on SVR4 actually.

So how is it Sun is permitted to open source Unix

particulars, but it has said it licensed additional rights in a 2003 deal in which it paid
SCO US$9.3 million.

The main problem with any of this is that all the companies that took System V made
changes to customize it for their hardware.

Though much of the later work was done by third parties and consortia, so even if
AT&T successor in interest gave the nod, those other parties might not have granted
AT&T the right to do this.

That's a good point, like many long-standing codebases, System V code is littered
with little "this is copyright this subcontractor, this is copyright that
contributor, etc." and big thorough license descriptions sitting at the top of source
files weren't in vogue at the time so it offers confusion over ownership with little
paths to clarity. Maybe a happy middle ground would be a 4.4BSD-Lite-ish approach to
System V in which anything demonstrated to be exact program text that is not out in the
open in the form of Research or illumos code can be scrubbed from, say, SVR4, and that
fragmentary codebase could then fly under the research license or CDDL or what have you.
As you mention though, what company wants to devote their resources to a revenue-less
project like that? It'd be swell if some sort of publicly funded organization like
the Library of Congress, Smithsonian Institution, or equivalents in other locales could
take up that mantle on this and other software preservation efforts. That's
something I think about often in my retro video game disassembly work, it'd be nice
to preserve these historically significant applications and systems as a formal career
rather than just hobby stuff. But right, where's the revenue stream to convince
anyone to do that, especially the legal hurdles involved? Lawyers ain't cheap...
