You're free to think so, but this behavior is ubiquitous among
Bourne-adjacent shells and is not about to change.

        % cat foo.sh
        export foo=$(false)
        echo "$?"

        % bash foo.sh
        0
        % ksh foo.sh 
        0
        % zsh foo.sh
        0
        % dash foo.sh
        0
        % yash foo.sh
        0
