Sorry to keep changing my mind on this topic, but I'd like to make one last alternate suggestion, which I think surpasses all the previous ones. Joachim proposed that what was called "bespoke", "standard", or "builtin" in the past be called "stock" instead [1]. I like this idea since:
1. "Stock" is a short, instantly recognizable English word, no matter where you live (I think). 2. It conveys the right meaning, as "stock" indicates something straightforward or normal (in contrast to GND and DAC, which do something a bit more novel). "Stock" has other meanings, but in this context I believe it's clear what it indicates. 3. It doesn't have the disadvantages of the other suggestions. Besides the points already covered, Joachim noted that "bespoke" has connotations of giving instances that would be tailor-fit for a datatype (e.g., "ignore field x in the Eq instance, because it is just a cached value that depends on the other"), when in reality, the strategy is far more mechanical than that!
