Not the best for a glue up.

I wondered about that as well. A really smooth surface won't soak
up the glue as well and you could squeeze out too much when
clamping.

There is a lot of back and forth on this. Typical yellow/wood glue
is not a good gap filler and works best with a minimum of product in
the joint. Tooth marks create gaps. Additionally there is a lot of
back and forth talk on starving a joint by squeezing glue out of it.
Glue starvation as it is often called is when there is no or not
enough glue on the surface to begin with not because you had squeeze
out. You get squeeze out because there was too much glue in the
joint to begin with. If you don't get squeeze out you have no
indicator that the joint is tight. I have never had a joint fail
because of too much clamping pressure and causing too much glue to
squeeze out. Remember, a quality glue joint line is one that is
almost invisible.

Yeah, there are a lot of old wives' tales in woodworking and those are
three of them.
Glue doesn't "bite" and holds perfectly fine to "buttery smooth" surface.

Try it with glass.

Does the bottle state the product works on glass?
Don't look, I'll tell you. No, it doesn't.

The glass comparison is totally irrelevant.
The glue doesn't work on many many things, but that in no way supports
your "smooth surface" theory.
