Its highly likely many/most? scripts will need to be modified to run
in Blender2.5 - so having to do edits for py3 is minimal effort if
your already updating your script for a new/modified api.
It is a con, but comparatively not a huge one IMHO. especially if you
consider we will move to py3 at some point anyway.

The proposals are in 2 parts, I only had pros/cons for including
python with blender.

I cross posted on blenderartist, where some scripters have replied.
