Then I misunderstood/misinterpreted: “… how grub2 can do less than
seabios …”.

I will.

Please let me understand your point better. I don’t see, why that size
difference is a problem?

Do you have a system where a 200 kB GRUB payload doesn’t fit? Did you
measure any speed differences? (But as stated, SeaBIOS loads/starts GRUB
most of the time from the a storage medium.)
