Well, yes, it's a sane idea.
Right now it seems a significant part of new threads started on this list
is about people doing --create --assume-clean with a different version of
mdadm (so offset/chunk-size/whatever is wrong) or they have the wrong
order. In order to help them, I believe the default behaviour of
--zero-superblock without any additional flags, should be to give hdparm
style message so that the user understands what is really going to happen,
and when the superblocks are zeroed, a mdadm --examine and --detail (if
the array is running) with a UUID/date should be saved somewhere.
The aim would be to drive two things:
People should think thrice about using --create --assume-clean. If they do
(or do --zero-superblock), detailed information should be saved for the
array and components before the operation was performed.
