Oh, absolutely, no question.

But (1) we are not there, yet (ZipArchiveInpuStream can read ZIP64 - did
I say that? - but we have no way to write them, yet) and (2) it will not
be sufficient.  Compress really is a jungle of dialects for almost all
supported formats and we need to do interop tests.

An archive created by InfoZIP is different from one created by PKZIP
which is different from Windows Compressed folders ... you get the idea.
If Compress' output matched that of InfoZIP it still wouldn't show that
we are able to read PKZIP created archives.

In the end I expect our corpus of test archives to grow as interop
problems are discovered.
