It's kind of an arrogant argument about not using something more advanced than your knowledge. It did not stop a lot of people from exploring things more advanced than their knowledge including young aficionados of computers themselves. There are a lot of areas of interest and knowledge. One can have knowledge of one area and not mastery of another related area. A better idea is considering how to better bridge what people with no or little mastery do not understand about Spamassassin. Efficacy is also based on usability. Spamassassin works better for some people but then if you don't figure out how to use it it doesn't work better for you.
One hitch is composing the dotfile or dotfiles. I would rather read about what people are doing to bridge any gaps for interested users who find the Spamassassin headers on their messages, only know a little bit of the jargon and arcane references in the introductory informational materials, would like to try to use the Spamassassin headers more effectively, and cull the spam type messages from their email more efficiently. Anyway if you can not get past someone's lack of knowledge, lack of mastery you should not be replying on this point. I am grateful for you interest and critique in the how to type of question in any case !
