I suspect that a lot of the fight about this is from Livingston people
not paying enough attention and/or from people complaining about it
not being explicit/emphatic enough, so in the hopes of clearing some
of the fog:

1. Routes to addresses assigned from the POOL are advertised as
intra-area routes if the pool IS in an area's range.

2. Routes to addresses assigned from the POOL are advertised as
external type 2 routes if the pool is NOT in an area's range.

3. Routes to addresses assigned by RADIUS are advertised as external
type 2 routes if the address IS in an area's range.

4. Routes to addresses assigned by RADIUS are advertised as external
type 2 routes if the address is NOT in an area's range.

#1, #2, and #4 are the Right Things To Do.

#3 is the problem.

Routes to the pool addresses are aggregated by the portmaster. Routes
to radius-assigned addresses could be aggregated by an area border
router if they were intra-area routes.
