Finally, I've posted a new version of cpio-mode at
https://github.com/dlewan/cpio-mode.
Here are the notes from the NEWS file.
Finds an appropriate major mode for an entry's contents.
You can now edit and save an entry's contents.
New dired-like commands:
+ cpio-entry-contents-revert-buffer (no key mapping)
+ cpio-dired-do-touch ("T")
