I agree that IMCR/IR should be taught in actual IMC whenever possible. Foggles are dreadful things which make it very hard to read the chart whole doing an instrument scan etc.
However, I found that a) no instructor was willing to do this, possibly because one cannot get RIS locally to me and b) no flying school plane I have ever been in would have been IFR legal in CAS, due to non-working (or non FM immune) avionics.
The avionics problem also means that if you are going to do an IAP on which you will hit terrain if the instruments are defective, no instructor will want to do the IAP in IMC. I have flown with DMEs which read a perfectly reasonable (but very wrong) figure and yet ident correctly, and same with VORs. But if a plane is flown VFR-only, these instruments don't officially need to work so don't need to be tested, which saves a lot of money on the cost of the maintenance. I know one local NDB/DME IAP on which such a dodgy DME will easily kill you.
