I may end up sending in a patch or two for these if I have some time.
I did note the discussion about what the LTS process looks like, which I
don't have strong opinions about but do want to make sure the project
(including folks on the security list) is willing to support. Other
than that, this series looked reasonable to me. I also confirmed that
it works with my existing sha256-interop-part-2 series, which I
appreciate.
I think once we have agreement on the LTS process, this should be good
to go.
