Not a protective layer, just a wet liquid layer. Fog in goggle is opaque
because it's a distributed noise of liquid points over a dry surface.
Spitting will create a thick film that "glue" to the glass (work better
on glass than on plastic) and that film collects the points of fog.
Being dissolved in the thicker film, humidity does not become
diffracting/white.
Issue of spitting: goggle accumulate a lot of proteins which make the
goggle more opaque. You need to use a bit of dish-washing product with
clear water after usage to get ride of the proteins. (So, it's "spit
before, wash with tension-active after"; Washing with only clear water
is a failure)

well, salt water diving will rot your equipment, so yes washing with
something like dish-washing soap is a definite must ... on "The Hawk" we
used to just throw everything in this big tub and someone else did the
"dirty work"

Cool, good to know. :)
SCUBA is something I'd always wanted to try, but unfortunately I
perforated my eardrum when I was 14 (diving accident - off the board and
slapped the side of my head on the water - I was able to whistle through
my ear afterwards, but then the pain it...Oh, the pain was *awful*), and
never went any further with it. I'd done snorkeling a few times and
enjoyed that quite a lot.

Opening your eyes underwater... I've never put my head under water with
my eyes closed. In a swiming pool, in a lake, at sea... all the same and
no problem and no pain at all.
Leting air out underwater, also a natural thing for me.
My only problem with swiming is that I float like a brick!

A very simple anti fogging tip:
Rub some saliva on the inside and do a quick rinse, put on and no fogging.

I disagree. Freestyle I find is much easier, because you can pause at any
stroke and just coast and breathe and float. With breaststroke, if you want
to stop, you have to actually stop swimming. I.e., you have to swim hard
enough to lift your face from the water with breaststroke.
For the "total immersion", you basically just have to get into a position in
the water where you're floating properly. You turn your head, and your face
is out of the water, and you can just glide like that until you stop. You
roll to the other side while drawing your arm back, and you go forward, and
coast to a stop with your face out of the water. Very relaxing if that's how
you want to swim.

Much worse is when your mask fills while you're doing SCUBA. It's not like
you can stop and rub the salt-water out of your eyes.

It's a chemical in your saliva. It doesn't work with other fluids.
Baby oil works too, btw.

I suspect that they didn't necessarily consider that part the "dirty work." :-)
