Only basic stalls taught in RA ???. Not necessarily true. The school where I learnt some 23 years ago insisted in competence and solo practice in all forms of stall except spins. An incipient spin is called a wing drop stall so is still ok in RA. On the other hand when I did my PPL a year later only stall to buffet or horn was normal with no full power on stall, no stall in a side slip, no stall in a steep turn. I still practice stalls from time to time and enjoy doing so. For what it's worth I recon that being ok with flying in and out of a stall builds memory to make sure you will never accidently stall. The other thing not often taught is that you cannot stall an aircraft without having full back stick (or near full). My experience is all aircraft have a "stall stick position" so if you don't pull back to this spot it will not stall.
