Also, just briefly looking at this, can you speak a bit about how the chain
links are different from field transformations? It seems like they're both
configurable mechanisms to execute pluggable code in an ordered manner over the
message. I mostly want to understand how they differ and if they differ enough
to make sense as a separate thing or if it may be worth-while to migrate them
to field transformations.
