I'm sure it is a pain to maintain, but consider recovery
with revision control in your root filesystem:

LILO: linux init=/bin/sh rootfsopts=ver:/bin/sh@@/main/1

Nice, isn't it? You can trash /bin/* all you want.

Distributed filesystems like Coda seem to get pretty close
to having revision control anyway. They need something like
it for conflict resolution.

The traditional revision control approach seems to get pretty
wasteful as well. Maybe you have a few dozen developers, each
with a few files checked out of a multi-gigabyte source tree.
The kernel solution has less trouble sharing resources among
all the developers, especially when people share a machine.
