I love having the stats as personally it adds an extra layer of interest to my reading experience. I can also totally understand jgoguen's stance in regards to this matter, and when all is said and done, it's his hard work and effort that has given us all the advantages of the extended drivers.
My solution (in case it helps anybody else in the same boat) was to downgrade my kobo to 2.8.1, and then use the current version of calibre (1.30 at the time of writing) with the most recent version of the extended drivers.
This is the last firmware that supported stats in sideloaded kepubs so using the above combo you get in book stats without loosing too much functionality (assuming that you don't use pocket).
Just make sure to delete the upgrade files from your Kobo before ejecting it, if you need to connect to kobo desktop at any time! ( see post 2 of this thread for more info on that
