Why do we point to a specific commit of deface?

This is a code archeology question for @RohanM

OFN is pointing to a specific deface commit.

At that time what was the purpose of the operation ?
Was it pointing to a commit in the future ? or in the past ?

Can we safely remove this constraint now ? (as it breaks bundler dependencies)

This is now outdated, we dont use deface any longer.
