As an author but one who didn't learn LaTeX at a tender enough age to be 
able to visualize the finished product off the source, I typeset very, 
very frequently. Yes, MacOS info would tell me but, by the same token, I 
could write my magnum opus as I used to do it ante 1980, that is with 
pencil and paper.

Far from me the thought of depriving you of your discretion.

But, forgive me from repeating it, as I wrote

    Errare humanum est.

    Specifically, I would forget to put the date in when I thought I was
    done, I would forget to take it out/change it when making a later
    change, etc. It would be a complete mess. That's why I like
    computers. They are dependably dumb.
