Google Page Speed tool complains about v3

[Ed]

When I use Google's Page Speed tool (great tool by the way
http://code.google.com/speed/page-speed/ )
to try to evaluate making my site faster, I get many complains about
Google Maps v3.

Specifically,
- external Javascript is not combined
- static resources are not served from a domain that doesn't set
cookies
- cookie size over the recommended 400 bytes
etc

the end result is my page gets a bad score :(

You can see the examples by running Page Speed on the demo pages like
http://code.google.com/apis/maps/documentation/v3/examples/map-simple.html

Is this something I need to worry about? I've heard Page Score is used
in ranking/quality scoring. it seems a shame to rank badly because I
use google's own map tools, especially v3 which is designed to be
faster than v2.

Thanks for your help and for the great tools.
