Post GPG keys in a machine readable format.
This is only partly a BIND issue, but I didn't want to email security-officer@.
Now it seems that the key is only buried in the HTML at https://www.isc.org/downloads/software-support-policy/openpgp-key/
Can the key please be reposted at e.g: https://www.isc.org/files/pgpkey2017.txt ? Scraping it from the HTML is icky. Yes.I get the irony of fetching the package src from ftp, and validating it with the key from https://, but it's better than not validating it at all :-)
