5,000 or 15,000 ft, it shouldn't make any difference if you know what to do...
Requiring 15,000 ft means that you are merely trying anything you can to get out of the spin. Also suspect wives tail.
Indeed it is the type of pilot, it's what the article is about.
I've been flying quite a few years and I've never come close to unintentionally spinning an Cirrus when flying from A to B but they seem to be able to manage it in the US frequently in these things.
A recent crash report in the US was that the pilot of the Cirrus banked too far at low speed when turning onto final and lost it. A pretty basic mistake really.
We lost one here at Warnervale in Christmas Day when it landed short of the runway. Standard trap of the Cirrus, so I wonder what happened to the insurance requirement for type training in Australia which should have covered that. With the dealer gone (I think) there may not be support for authorized Cirrus centres regarding type training any more.
We could easily go down the same path as the US with this aircraft. We've already lost a good number of Cirrus here.
