There are two backward incompatbile changes, both minor. First of all ZipInfo will lose the fileoffset attribute because calculating it when opening a zipfile is very expensive (it basically requires a full scan of the zipfile). This should be harmless, I couldn't come up with a usecase other then reimplementing the read method outside of zipfile. Not knowing anything about this, why not implement fileoffset as a property?

That is possible but would introduce a link from ZipInfo instances to
Zipfile instances and would therefore introduce a cycle. As Zipfile
has a del method that's not something I wanted to do.
