2) We already need a working copy format bump for the pristines-on-demand feature. So using that format bump to solve the SHA1 issue might reduce the overall number of required bumps for users (assuming that we'll still need to switch from SHA1 at some point later).
Using a new hashing algorithm in the working copy is relatively simple. Making such a change backwards-compatible is not. It would be really nice if this could be done in a way that allows newer clients to still support older working copies without upgrading them; after all, we have the infrastructure for this in place now.
