Well, the Monte Cristo has been a tradition at DL since the sixties. If they removed it, there would be a "Save Mr. Toad"-style war going on between the locals and Disney.
Not to mention most of DL's audience is locals who live within an hour of the park. It's not comprised of mostly tourists like WDW is, so the locals have been having Monte Cristos for years, every visit they make sure to grab one.
Monte Cristos, much like the non-alcoholic Mint Juleps here at DL, are institutions. If they were smart, they'd send them to WDW.
