[Question] Why not load compressed kernel?

[y.volta]

Hi,

    I'm trying to load a .gz multi-boot kernel file. but, I get 'invalid magic 
number'. and when i check the grub_rescue_cmd_linux (), it uses grub_file_open 
() not grub_gzfile_open ();

    So, my question, why not use the latter one for reducing the file size?
