Type 7 LSA default-originate always

All,

I was doing some labs today and could not find a place to do a
default route into OSPF (NSSA area) with the always option.

NSSA ASBR
area 1 nssa default-information-originate has no "always" keyword

STANDARD ASBR
default-information originate always

Is it a correct assumption that only Type-5 default routes can be
kept in the routing table in the instance of a flapping default route
on an "upstream" router but Type-7's (or routers in an NSSA) cannot
keep a default route in case of a flapping default route?

Regards,
Nate
