This is great advice, and not just for builds/CI configuration.
I made a similar suggestion recently to clean up the starttls-everywhere
datafile updater:
https://github.com/EFForg/starttls-everywhere/pull/65/commits/eb0a28e3fa141d4fb445c00df3ab7f3765ded859
In some ways, the keyserver network has done the OpenPGP community a
disservice, by encouraging OpenPGP users to refer to keys by
fingerprints (or even worse, by key IDs). While this is a useful
shorthand in some contexts, it's really a security/reliability
anti-pattern when it comes to secure programming.
