The Archive Mounter is a much better idea than auto-extracting, but is it ready for widespread use? Choosing "Open with Archive Mounter" with an archive does not change the current directory in Nautilus, and if you blinked, you would have missed the archive being "mounted" as a drive in the Places sidebar.
Automatically changing the directory to the mounted archive would make this a lot more user-friendly, but the idea of "mounting" and "unmounting" archives still seems quite strange (and would confuse new users, I think).
