Hmmm, they say :

"MySQL Connector/Python enables Python programs to access MySQL databases, 
using an API that is compliant with the Python DB API version 2.0. It 
is written in pure Python and does not have any dependencies except for 
the Python Standard Library..."

i guess with Oracle connector there could be one advantage - they will 
try to be most compliant to their product in every aspect as they would 
raiser promote their DB instead of discouraging from it.
