That sounds like a terrible plan. We should make newer hashes the default, and we can make tools print a warning if sha1 is used where it shouldn't, but please don't break things on purpose. For many many things sha1 is just fine. Just like md5 or even crc32. Not everything is about cryptographic security. Also, users will want to verify old signatures essentially forever. This should be always possible. And finally, the world is huge, and other users will provide sha1 signatures no matter what we do, and it is better to check those than to completely ignore them.
