Excel has a history of forced format updates, breaking incompatibility. I know people who banned it because they got tired of marching to MSs upgrade beat.

Python 2 to 3 upgrade aside, can’t really say the same about the language.

There are a number of good arguments out there that might violate an engineers perception, which one might call a cognitive data model built through training and experience.

There is no theory that makes any given engineering path “wiser” than others. Just engineers chasing incentives to be engineers.

Libraries introduce breaking changes, too. I’ve been bit by silent default changes in Pandas, for example. To me that’s kind of striking because I also wouldn’t consider myself a major user of the library.
