Because it would be no use at the time the prompt is printed: after
the last command.
You can use the trap builtin with the faux 'DEBUG' signal though to
execute a command just before a command is executed, and $BASH_COMMAND
will tell you what that command is. Here's one way to put this to use:
trap 'printf "\e]0;%s\a" "$BASH_COMMAND"' DEBUG
