Michael,

So far, I've downloaded source for emacs 26.1 and built it
(in a somewhat hobbled development environment -- no X development,
no image support, without gnutls).
I've loaded tramp and url-tramp and opened test files (with names ending in
'.cpio).
All I get is "File not found and directory is write-protected".

I assume I'm missing something. Can you help?

Also, a quick look suggests that libarchive may not be universally
available.
I'm a big fan of portability, if it's possible, so, if that's the case,
then I might prefer to avoid it. Any thoughts?
