I'm a little late to this conversation, but this is my take on the subject. I received my training 50 years ago in the US. Spin training was an intensive part of the training. Within the first 10 hours of dual, a stall and spin was required every session before solo. All this was in a C152. After a couple sessions of solo, a required solo spin was required over the airpark in plain sight of the binoculared instructor. I've had to use that training twice since. I hate to think of the outcome if I was not prepared. It's scary even if you know how to recover from one.
With so many planes today, stall characteristics vary from type to type and there are some that are so mild, it's almost un-noticible until it happens. To late then to figure it all out. I've never done an acrobatic maneuver in a plane. It's never been my mission.
My nephew is a commercial Ag pilot with a whole lot of hours and has never received spin training. He said he never flies above 700 feet, so he wasn't taught because it wasn't at a recoverable height. Most of his flying is below 300 AGL.
Experimental homebuilts are not spin tested, typically. Going into a spin in one that might break up after spinning for a couple thousand feet, probably would be recoverable the first few hundred feet, if you had the knowledge.
Get spin training wherever possible. It sure takes a lot of tension out of things when you are right at the envelope.
That's my 2¢.
