pup/wup != os3 :-p
Well, if you are going to play with semantics...
Remind us all exactly which WOS/PUP applications worked
without OS3.x. Or failing that, remind us how either of these kernels were able to run as freestanding operating systems without OS3.x being involved.
IIRC, both
kernels needed Kickstart 3.1 just to get out of bed. WOS and PUP may have been multitasking kernels in their own right, but they were totally dependent on OS3.x for everything from initialisation upwards.
