As I was treating my Faggin w/framesaver this morning, I noticed that the top tube is not open at the seat cluster. The only opening into the top tube is inside the head tube. Does this signify anything about the framebuilding process? A mark of higher or lower quality construction, perhaps?

That is normal. IMHO it helps in clamping the seatpost.

I noticed the same thing when I was applying frame saver to my trek last night!

I also only plugged the head tube and the bottom bracket. I didn't plug the seat tube. Today I'll spray a second coat in there and plug the seat tube and leave the bb unplugged and flip the frame upside down on a stand. Figure it'll wear evenly that way.

The ones I've had that were open were on internal TT cable routed frames where it helped to be able to stick your finger in to guide the housing/cable.
