Couldn't agree more. Underlines that most domains don't spring from the rm, even though there seem to be lots of people who believe they can create one in sql.
Regarding the comment about standards being useful, I'd say they are sometimes, somewhat useful, sort of like rough arc welding versus really precise tig welding (you didn't mention which kind you had in mind). I do think there are instructive comparisons with a machine shop where physical facts force certain techniques. When it comes to software, it amazes me how dogmatic some people, like the standards worshippers, can be when the sky's the limit.
