Subject: SHA256 support not experimental, or?

Hi all,
Is sha256 still considered experimental or can it be assumed to be stable?
The usecase here is we are planning on moving to sha256 repositories
mostly due to integrity guarantees, hypothetical or otherwise. What is
important is not the initial interop challenges with sha1 repos, but
whether the on-disk format will remain compatible with future versions
of git. At minimum, the on-disk format would be converted by some future
version(s) of git into another one and not be an end-of-the-road because
it was "experimental" where dataloss is an implied risk.
Attached is a patch that removes the scary text, if indeed sha256 should
be viewed as stable.
Cheers,
- Adam
