default branch. Gregg just ran out of time before he was ale to add I2
First, thanks for the details you posted.
Second, to answer your question: yes it makes sense to add checksums to I1
today since it should hopefully not be a lot of work and would allow things
to work again.
Then, adding I2 support is obviously a next goal, but that's bound to be
more work so it shouldn't be blocking just adding checksums for I1.
That, I have no idea.
