This sounds similar to the approach to taken with Replication for years
before being moved into core.

Just like replication, pooling has different approaches.  I do think
that in both cases, having a solution that works, easily, out of the
"box" will meet the needs of most users.

There is also the issue of perception/adoption here as well.  One of my
colleagues mentioned that at PG East that he repeatedly heard people
talking (negatively) about the over reliance on add-on packages to deal
with core DB functionality.
