In the classic "the mythical man month", Brooks describes 5000 man years effort in delivering OS/360.

I think by any measure that OS/360 would be "high craft".

Consistently, at scale, and in a durable way: I doubt it. However, I have seen many localized cases of extreme excellence in the places where the company knows it really matters.

Apple’s hardware side seems pretty great at it. Software maybe less so.
