Is there at this point a solid plan for how SHA-256 repos will support
access SHA-1 only clients?

I remember reading a discussion of having a table somewhere that would
translate SHA-256 to SHA-1 when needed.

Documentation/technical/hash-function-transition.txt has flushed out
the necessary details?

Yup.  The design there sounds very simple and it is, conceptually, but
practically implementing it is quite complex.

You can pull the in-progress work from transition-interop on my GitHub
remote to see where some of the complexity lies.
