Funny thing is, if you look at codebases of some opensource projects [1] doing complex and ambitious stuff, written by some real experienced engineers, you’ll see the common „dogmas” (don’t have long classes, don’t have long methods etc. etc.) are not obeyed. And yet, they shipped very complex and successful software. It’s almost as if these rules are mostly arbitrary and don’t really matter.
[1] I’ve noticed that in codebases of Apache Spark, Apache Oozie, Apache Cassandra, and Firefox.
