I have this feeling that "automatically enabled" flags could somehow have an ephemeral nature, where a flag would be enabled at build time, and then later a subsequent change in the graph toggles the flag off, creating a potentially undesirable rebuild. I feel I might be imagining a problem because I might have a wire crossed somewhere, so some sort of confirmation that I'm the insane one and this can't happen would be reassuring :)
