Possible. It's up to people to decide if they're OK with a known 92% collision out there (with the unknown being there could be a 100%), or go for something stronger.
Thanks, you have this exactly right. The unknown part is especially worrying because we didn't implement many of the strongest ways to make to the final stretch yet, i.e. Wang-style message modification. Our result is basically a very strong direction in this cryptographic research, but not a full break yet.
