core is very size sensitive. You need a valid usecase to justify such a
feature in it. It feels like useful only for dumping a mass of info. In
practice users can only report back around 4-5 lines, sometimes a
compelete screen by taking its picture, so this info would be lost in
bugreports anyway. If you're developping something you usually need a
dump in that exact place only once and then using grub_printf is usually
easier.
