To quote the maintainer in another bug.

--- The reason is that these settings make no sense. Why should a terminal be transparent, or have an image behind everything, but the same not apply to, say, gedit, or firefox, or evolution?

That's the problem with self-proclaimed usability experts. They see the word "consistency" and think to themselves "Oooooh, I shall make everything consistent".

This is why in Gnome, all tab bars are on top, including in the terminal. Consistency for the sake of consistency.

Terminals have only text, sometimes lots of empty space, never images. The transperency makes it look nice and people (that care to enable it) happy.
