Debian pack of p7zip contain a /usr/bin/p7zip file, which is bash script, named "gzip-like CLI wrapper for p7zip":

#!/bin/bash
# gzip-like CLI wrapper for p7zip
set -e

compress=true
file=

usage ()
  {
    echo "Usage: $0 [-d] [-h|--help] [file]"
    echo ""
    echo "    -h print this help"
    echo "    -d decompress file"
    echo ""
    exit 1
  }

while [ "$#" != "0" ] ; do
  case "$1" in
    -d) compress=false ;; # decompressing
    -c) echo "$0: ignoring $1 option (not yet implemented)" ;;
    -h|--help|-*) usage ;;
    *)
      if [ "${file}" = "" ] ; then
        file="$1"
      else
        usage
      fi
    ;;
  esac
  shift
done

# make sure they're present, before we screw up
for i in mktemp 7zr rm cat tty ; do
  if ! which $i > /dev/null ; then
    echo "$0: $i: command not found"
    exit 1
  fi
done

if [ "${file}" != "" ] ; then
  if ${compress} ; then
    7zr a "${file}.7z" "${file}"
    exec rm "${file}"
  else
    case "${file}" in
      *.7z)
        7zr x "${file}"
        exec rm "${file}"
      ;;
      *)
        echo "$0: ${file}: unknown suffix -- ignored"
        exit 0
      ;;
    esac
  fi
fi

tmp=`mktemp`
trap "rm -f ${tmp}" 0

if ${compress} ; then
  if tty -s <&1 >/dev/null ; then
    echo "$0: compressed data not written to a terminal."
    echo "For help, type: $0 -h"
    exit 1
  fi
  rm -f ${tmp}
  7zr a ${tmp} -si >/dev/null
  cat ${tmp}

Sometimes someone can use it.

Would it be better to change this package?:
https://www.archlinux.org/packages/extra/x86_64/p7zip/

Is it better to add Troubleshooting to the wiki, which informs about this difference and instructs how to add this script?:
https://wiki.archlinux.org/index.php/P7zip

Arch doesn't patch packages, it ships them as upstream intends. Our package won't get patched and there's nothing to troubleshoot.

Sapi4linux uses debian p7zip. (Gzip-like composition).
Because of this he does not work on Arch.

Did you just submit this bug to the p7zip package?

This isn't a bug with Arch. And this isn't something to add to the wiki.

If someone wants to add the package to the AUR, they will work out how to unzip it.

That's a Sapi4linux problem, not an Arch problem. Depending on something so distro-specific is irresponsible at best.
