On a philosophical level: It's surprising to me in that previous example
that if `async-shell-command-display-buffer' is t, the buffer is /not/
displayed (according to `display-buffer-alist'), but if it's nil, it
/is/ displayed, eventually (ignoring `display-buffer-alist').

On a practical level: The user may want to differentiate buffer display
behavior based on the name of the shell command buffer or by some other
predicate, including disabling showing that buffer, regardless of
whether `async-shell-command-display-buffer' is set to t or nil.  I have
recently authored a package to make this easier [1] and ran into this
problem.  The example configuration in the README might shed some more
light on the expected behavior.
