The last sentence already make clear that it's not part
of the tutorial. "How To" is a different style of document
which is important to have, but serves a different purpose
compared to a tutorial.
See https://www.divio.com/blog/documentation/ which I
found very enlightening. The talk is great and explains
things in detail, but the main point is the 4 different
types of documents shown in chapter "The secret".

That's a great point. I think there's quite a number of
cases where people complain about "OpenSCAD is unusable
slow" while sticking a $fn = 200; at the top.
I think one thing for the tutorial might be to not really
teach $fn, but always show $fa and $fs.
Special optimization topics could maybe be part of the
tutorial but I suspect the limited time frame will mean
it's not going to happen as part of this GSoD session.
It would be nice to collect ideas about this kind of
topics somewhere though. Maybe just as wiki page in one
of the github repos.
