can we please avoid the phrasing "impossible" or "not possible" or "won't work" on design docs and slack chat? i'm not going to jump on you for saying it, so you don't have to care, but it's a little confusing for me when i see a design doc that i haven't seen before, and see the words "not possible", and i don't know whether: (1) there's a ton of background that means i shouldn't bring it up, or (2) whether this just hasn't been talked about yet. this goes in line with other general strategies for writing effective design docs. my strategies are devoutly different than others but this still applies
