design-choices is probably my favourite tag on this site, but its name has been bugging me for a while. I feel it is not particularly self-explanatory, and this contributes to it being underused by askers to whom it's not readily apparent what it's for. I often see an opportunity to apply it to questions after they have been already submitted.
More worryingly, I recall it being misapplied at least twice, most recently in https://retrocomputing.stackexchange.com/revisions/22478/1.
Can it be renamed to something like design-rationale?
