Personally I think every pilot must experience spinning at some point and that the basic spin recovery for the type you are flying should be burnt into your memory.
My first CFI used to say" you only know the recovery well enough if I wake you at 2 in the morning shining a torch into your eyes shouting 'spin recovery' and you can trot it out exactly."
Spinning should never be taken lightly as an excercise which is why I wouldn't want it to be a mandatory part of the syllabus, but doing it voluntarily in a type that is capable and with an experienced Instructor is something I try to promote.
