I left the text before as indicative and human readable but
unfortunatelly that's not complete.
The list of all primitive functions contribute to the eln linking
mechanism we use and is accounted in this hash. Also we can trigger the
generation of a new hash each time we deploy an eln ABI breaking change.

That's easy, we should just pick a lenght we like.
