It's very very rare that anyone needs to care about endianness outside of the application edge space (ie. reading or writing to data sources and sinks). In the article, many of the errors were a result of undefined behaviour that just happened to work on the CI machines upstream Qt ran. Relying on undefined behaviour in your code will bite you in the bum sooner or later, regardless of endianness.
