Because it should be "plug and play", not "plug > and don't break things". Look at any PCMCIA system. There are six flavors of "enpic"'s for PCMCIA which do exactly this. Plus per "slot" power management. There are also several ISA motherboards that *only* obey the card disabling interface. They do so by using reserved PNP board IDs, one per slot, and only do the enable/disable, no remapping (at least I have never seen one that actually did remapping).
