What is missing here is any benchmarks backing up this argument for code structure.

Of note, as of C#9 (and maybe prior), the dotnet runtime does this automatically whenever it is deemed safe. https://devblogs.microsoft.com/dotnet/performance-improvemen...

The same technique is applied as an optimization, when deemed safe, in all current gen c compilers (gcc, llvm, etc).

I'm very confused why neither measurements nor references to when this is done automatically in most modern languages is included in the article.
