This is silly.  It also means that character protrusion (HZ algorithm)
is deprecated.

And maybe the left and right margins shall have the same size, the
preferred fonts are Times New Roman, Arial, and Courier, etc.

Ignore these idiots.  If in doubt, simply use your brain.

Typography is about optical appearence.  This means that descenders
should stick into the margin.
