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).
