It has a different application-visible ddraw format. The reason why I added the new format is that we have to convert in both directions and make sure we never tell the app a surface is D24X8 when it requested D24 or vice versa.

The alternative is to just change the current ddraw format of D24X8 into how my patch describes D24, but Windows actually advertises both formats, and I think we should do the same.
