They all use the qemu terminal emulation and render the chars on a
displaysurface.

Why is this odd?  gtk *is* different, it takes the character stream and
sends them off to the terminal emulation widget.  That allows to do
stuff vc can't handle by design, for example placing vte in a new window
instead of a tab so you can watch vga and serial console side-by-side.
