Well, that's true for some failure modes.
However, if the vacuum side of the diaphram starts to leak a slow leak, it'll drain down. It also sucks gas through while running, but it's not as noticed if it's slow enough.
BTDT on my Cougar, albeit at the EFI pressures.
(A quick test is to sniff the vacuum side while the motor's not running; if the diaphram is leaky, it'll smell like gas.)
