True. Except if you are someone like DOSBox or FreeDOS and want to know how/why some quirk happens in MS-DOS that makes some program go, but not in your code, now you can figure out what's up.

In reality, getting the Windows source released so that the Wine team can do this would be much more useful. From what I understand Windows has a lot more undocumented but widely used API's that Wine tries to emulate by trial and error. Instead of having a complete emulation they break it down by which programs it can and cannot run because of these hidden API's.

This is definitely a publicity stunt, no question about it. It still provides some very minimal value and perhaps this is MS dipping their toes into the OSS water when it comes to old commercial products.

Or if you're the ghost of Gary Kildall, and you want to find out whether Tim Paterson and Bill Gates really did rip you off or not.

MS-DOS has been disassembled and reverse engineered to death by these teams, and there's little if anything at all left to discovered.

They have the x86 assembly code.

What they don't have are the comments.
