Fair enough.

Splitting libarchive outputs is sadly a core-updates change, but we
could hide the existing one and add a user-facing one with the split if
that's what you desire.  I don't think adding a package for just the
tools has merits.

I think these could be shortened as follows:

This package/the 'bin' output also provides
@itemize
@item @command{bsdtar} and @command{bsdcpio} to pack/unpack archives
like @command{tar} and @command{cpio} respectively, and
@item @command{bsdcat} to concatenate files like @command{cat} does,
while transparently unpacking archives.
@end itemize

WDYT?
