Wrong. They are not ignored. They are used to define the DEFAULT
environment.

You misunderstand how the environment works. There are no two
separate sets, it is only one set, which gets pre-initialized form
the default settings, which get used in case of corrupted checksum or
so...
If you cannot fit your environment in 256 bytes you should use a
bigger EEPROM. Or even better (much more reliable) put the
environment in flash.
