I don't think it's better.  CFG_BOOTMAPSZ  is  a  hard  coded  limit.
initrd_high  (or fdt_high or whatever you will call it) allows you to
use the same value as default, but  overwrite  it  on  systems  which
don't  need  it  or have additional restrictions, i. e. it giveds you
added flexibility. This is IMHO a Good Thing (TM).

Best regards,
