 Here are the reasons:

- update-defconfig doesn't exist for all kconfig packages

- update-defconfig is preferred if it exists (for Linux I certainly see no
reason to ever use update-config)

- documenting foo-update-defconfig would perhaps be better, but that's part of a
bigger change that would completely remove all the specifics. When I did the
'make help' patches I started on that, but it turns out to be a bit more work so
I dropped it in the end.

 Arnout
