Good idea to display the flags, but the characters aren't really
very self-describing. Should we prefix each with an f maybe?

Honestly, I don't care.
Just wanted to stick with the one-letter acronym like all the others
did.
But in the end having the failfast ones prefixed with an 'f' sounds
reasonable.
Cheers,
Hannes
