I don't think that's a valid assumption.
Perhaps they listened, investigated, and said no, for many of the reasons given in this thread. Or, perhaps they decided this is the greatest idea since sliced bread and are adding it to our development plans.
I find it sad that posts like this and so many others in the forums post suggestions, and then denigrate the product if there suggestion is not accepted and implemented immediately.
I'll admit there's no impact to me; I'm an apple user with no access to SD cards.
