I already have been archiving "my" stuff from etherpad on wiki, of course, and I've never ever used etherpad.wmflabs.org because I knew everything in Labs can die any time, but this doesn't mean that I don't worry for what others will lose. Of course I understand it's not the _responsibility_ of Labs folks nor ops, but still it would be nice if someone managed to do something about it. If I was provided with a list of all existing pads I could do something myself; I only found few links from our wikis https://toolserver.org/~nemobis/tmp/ethlabs.txt
