Nuanced, but I’ve heard “don’t let perfection be the enemy of completion”, which is real in the cases of not shipping because one is constantly polishing/perfecting, or, as I heard sitting beside phk[0] at BSDCan commenting on rejecting some environmental sensors into FreeBSD, something to the effect of “We need ‘good’, not ‘good enough’.”, which draws a line at accepting janky “solutions” that are architecturally weak, or otherwise look obviously problematic.
