there was a similar discussion regarding roadsigns there in Norway (or perhaps it was Denmark ). The discussion was about whether to upgrade the the old "beware of train" road sign (a pictogram with a steam locomotive). The logic was the same as with the floppy icon - why have a pictogram mimicking an object that is no longer in use? Creating good long lasting pictograms is not an easy task. Recently they tried to create a pictogram meaning "this is a toll road where you automatically get a bill in the mail, do NOT stop" (a camera takes a photo of your licenses plate, you do not need to slow down and cause traffic jams). The pictogram they came up with, was so weird that is looks like some sort of scary warning and the result is opposite - people stop and wonder what is this all about.
