I’m sure the plane will fly a lot slower with CAPS deployed 
Why can’t the just call it BRS? What do they call the wings? Cirrus Airframe Aerodynamic Lifting System ?
CAPS is a system developed by Cirrus & BRS together and is not in all details identical to other BRS systems. So why should they not give it their own name? Since CAPS is very important for the Marketing of the Aircraft it is unerstandable that they did that. It is also: unimportant :-)
To return to the original question: there has been much emphasis on the wing, however the whole airframe gets cleaned and polished, including prop, antennae etc. Maybe the dead insects on the prop have a different effect than those on the wing?
It gets washed every few months and gets a polish annually, and it definitely goes faster after the polish. Perhaps people who notice no difference have very clean aircraft in the first place!

Well it’s not that their marketing department tries to convince possible customers that Cirrus is introducing all those features into aviation. If you examine this further, you will find out that they did very little “firsts” – but they have an economically successful marketing and obviously picked a good list of items to integrate into a product.

Depends on the money and the weight! 
A gazillion pilots have flown and fly without “CAPS” every day.
Why are we talking CAPS in this topic by the way?
Then again these two must really be praising da chute:

NASA has gotten interested. I suspect because of a certain thread on a European aviation forum:
Why airlines hate squished bugs on airplane wings
0.5% fuel savings, or $240 million dollars.
Speeds not typical for a GA environment, but nevertheless interesting.
