Yeah, firefox/mozilla's messaging is that they're weak and "planned to
be removed at a later" time. But www.amazon.com still works as far as
an end user is concerned in 32.0.x and 33.0.x even though those are
marked as weak. They're still in the mozilla bundle and firefox will
still use them. By excluding them from the curl bundle, though, amazon
and aws just broke hard for consumers of that. I'd say that you've
gotten too far ahead in anticipating dropping the 1024-bit RSA certs
since breaking AWS is a total show stopper for a lot of people -- which
is most likely why mozilla marked them as weak and didn't drop them
completely like the other 1024-bit keys that were totally removed.
