I think so. You seem to be saying that, because cursor-type is a
buffer-local variable, setting it in the minibuffer would only change
the cursor in the minibuffer itself, correct? Do you know this for a
fact, or would you say it's more of an "educated guess" on your part.
If you're right, you wouldn't be able to change *any* buffer-local
variable using M-x set-variable.
