I think I understand now. I also see that in far future KZIp could support ACL 
(access control lists) and we would have the problem again and in a increased 
form, as it would not be a fixed size.

So yes, it is better to decide to keep the "bare" fat format.

However, what I am wondering now, is why this issue has come up months later. 
(The KZip commit was in February.) Are files ending in .kwd not recognized as 
KWord files anymore. Is there another bug somewhere?

(You could test by extracting a maindoc.xml from a KWord file and renaming it 
as maindoc.kwd. It should be a KWord file, as KWord should be able to load 
raw KWord XML files.)

Have a nice day!
