Impedance mismatch? "Just keep on doing that" refers to automatic,
silent WC updates. :)

I cited the MD5 index as a case where you definitely want the update to
be automatic.

Now ... do we want to come up with a WC versioning scheme that allows
partially automatic updates (e.g., for changes that are
backward-compatible, such as adding a new index) but requiring manual
intervention for incompatible changes? Maybe. Doing this would certainly
make the code a lot more complex, not just the update part but also the
requirement for newer versions to support (and emulate all the quirks
of) older WC(-NG) formats.

I'd want to think very, very carefully about doing this, maintaining
such compatibility is likely to be quite tricky.
