Should include an image genesis label?

[kbaegis]

As I think about this, I was considering adding a new label that would be great to see on images globally. Every time FROM is called, I would like to append to a genesis value.
For example:
FROM alpine:latest
...
COMMIT alpine.altered:latest
FROM alpine.altered:latest
...
COMMIT alpine-with-netconf:latest

ENV image-genesis="alpine:latest;alpine.altered:latest;alpine-with-netconf:latest"

May or may not be useful for this standard, but I thought I'd chime in.
