It seems dehydrated doesn't actually make many of the variables from dehydrated --env available to the hook scripts. I've ran across this with DOMAINS_TXT missing - adding it to the export line seems to fix it, but there's probably others that should be added here too.

Not really a bug, but probably bad wording.
dehydrated --env is available if (for whatever reason) you want to export the dehydrated config parameters for use in other scripts (e.g. a wrapper script which reuses the same config) or for debug purposes.

Adding those exports might also require some documentation since some of those variables would then be certificate/domain-set specific, but only for certain hooks before they return to their original state, while others are valid for all domain-sets.
Since I'll be restructuring a lot around that config behaviour I won't add the exports right now, but I'll keep this issue open as reminder to add them later.
