Thanks for working on this.  I wonder if we should disable it by
default in "make menuconfig" for a year or so prior to full removal?

Well, I think the only thing this code does at this point is confusing
people.

I also have a small compatibility story:  seabios got build-in serial
console support a while back.  We never managed to add some kind of
automatic switch-over from sgabios rom though (there only is a sanity
check to make sure they are not both active).  So the code got little
actual usage for quite a while.  Roughly five years later qemu and
libvirt did a hard switch-over from sgabios to the seabios build-in
serial console.  No compatibility problems.

The qemu versions which depend on this code are more than ten years
old meanwhile ...

take care,
  Gerd
