(Shrug...) “Who knows? The past will always be with us...”

Makefile.PL started the ball rolling, and Builder sprang out of that and says that it's better. Whether or not it is, today we've got both. (And tomorrow, we'll also have “both.”) As an Implementor, evaluate both of them, and decide for yourself which one feels better to you today. Whatever you decide, it'll surely be a good decision for today. Over time, one-or-the-other will gradually fade out. (Maybe.) In the meantime, both of them will do the job. So, “no worries, mon.”

It's really a waste-of-time to ponder how the future will judge your decisions.
