Yes, I think this is an excellent idea. It should have 
--please-destroy-my-disk, and if there are existing superblocks, it should 
save the contents of mdadm --examine before overwriting or zero:ing them.

--assemble --force should list the drive event count and say which drives 
have differing event counts and ask for confirmation that this is really 
what the operator wants to do. If the event count differs more than 50 (or 
some other value), there should be a requirement for 
--please-destroy-my-array to be added :P

--assume-clean is great for those that need it, but for the great majority 
who rely on google and wikis it's a data-destroyer.

I agree.
