I posted this as a comment by accident, but here is my initial opinion
I’m actually torn, its annoying when a site doesn’t work properly and I’m forced to use IE6 because of work. That said I don’t know if that means I think that it should or shouldn’t be coded for. It’d be nice if everything worked, so from that perspective I think that it should be coded for. Another part of me though thinks that the only way for it to actually go away would be if enough stuff just stops supporting it. One of the main reasons that Windows XP stuck around for that long is that support kept remaining for it .. if that had not happened others would have migrated away from it. Same thing could be true here too
