We've talking to split files (e.g. 1 file per 1 function or per 1 method), not to separate tasks or factor tasks. Java can't split many methods of a class to many files, only 1 file per 1 class, not 1 file per method. > And again you're missing the point (with your comment about future GCCs > that I accidentally snipped).
