64-bit Audacity 3-2-1 offers me my 32-bit plugins on the Realtime effect list,
if I choose any of these 32-bit plugins, 64-bit Audacity 3-2-1 will immediately crash.
Until 64-bit Audacity can use 32-bit plugins, (via a bridge/wrapper),
32-bit plugins should not be visible to users of 64-bit Audacity.
