Secondly, there are no optional flags listed in the 2008/2013 version

POSIX 2004 might be "older" but it is the version referenced by Debian
Policy - as per
<https://www.debian.org/doc/debian-policy/ch-files.html#s-scripts>:
"Scripts may assume that /bin/sh implements the SUSv3 Shell Command
Language[90] plus the following additional features not mandated by
SUSv3
[list that doesn't mention "command"]
If a shell script requires non-SUSv3 features from the shell interpreter
other than those listed above, the appropriate shell must be specified
in the first line of the script (e.g., #!/bin/bash) and the package must
depend on the package providing the shell (unless the shell package is
marked "Essential", as in the case of bash).
[...]
90
Single UNIX Specification, version 3, which is also IEEE 1003.1-2004
(POSIX), and is available on the World Wide Web from The Open Group
after free registration.
"
checkbashisms's handling of "command" appears to be in line with that
Policy requirement.
