I am re-opening with the scope limited to source code that will not be part of a doc review.  The 2nd PR falls within this limit and I think it should be properly reviewed.

I am opposed to removing 'sanity check' as it has a well-enough defined meaning within programming that does not disparage the code author.  Indeed, sanity checks are often written and labelled as such by module authors.  PR9335 does not touch this phrase.

The other terms are more often applied to code by others, sometimes with a hint of disparagement of the author.
