Related, though not responsive to the OP's question, I include a
variable, "ShellLevel", in PS1, which is set in .bashrc.
	ShellLevel="$(/bin/tty | /bin/tr -dc '0-9').$((${SHLVL}-1))"
That puts a number of the form X.Y in the prompt, where X is unique for
each window and Y increments by 1 for each subshell.  I can keep track
of windows and know whether or not typing "exit" will make the window
disappear.  If I've only one window open and no subshells, the prompt
looks like this:
	0.0 /c>
(I've also got "\w" (the current working directory) in the prompt.)
