MakerDAO stability fee reduction

After many months of increase, the DAO has voted to reduce stability fee by 2% making it 17.5% per annum. This was a direct result of the DAI hovered very closely to USD1.00. Question is why change while it ain't broken? My best guess is for data gathering and scientifically proof the economic model of decentralized stable coin works.

Therefore, it could be when certain conditions are met, the stability fee adjustments can be a swift one time increase rather than a gradual increment of 2 to 3 percentage per round of governance voting.

On another update, Loanscan.io interface changed recently and I noticed Compound v2 on the list. Curious but will do a bit more digging to understand the difference between version 1 and 2.
