These are all in the shell-versions toolkit I recommended.

    docker run -it --rm alganet/shell-versions:all /opt/mksh_R59c/bin/mksh -c 'echo $KSH_VERSION'
    docker run -it --rm alganet/shell-versions:all /opt/oksh_7.9/bin/oksh -c 'echo $KSH_VERSION'
    docker run -it --rm alganet/shell-versions:all /opt/loksh_7.9/bin/loksh -c 'echo $KSH_VERSION'
I omitted them from the post because this is not about the history of ksh and the pdksh codebase.

The POSIX commentary mentions the Korn shell ten times, including particular behavior of the 1988 ksh release. Bash is not mentioned.

It is easier to understand the POSIX standard with a ksh focus, particularly ksh88.
