This is not always possible and a little short-sighted, especially when you are on a large, complex, established project with many contributors, where "just refactor 1.5 million lines of code, spanning 1500 files that have evolved over a 10 year period" is just something not open for debate.
In those cases, and in the cases where a single large file just makes more sense or is unavoidable (IaC/build scripts, shell/sql/migration scripts, config files, etc.), the author's methods are absolutely valuable.
