I do not think that this is the case. SpriteOp has changed 
tremendously, even in much more recent times. You are probably right 
as far as the kernel SpriteOp calls go, but not the ones offered by 
SpriteExtend, which are the ones used for rendering nowadays.

Yes, of course, but that is exactly my point. So, it can hardly be 
argued that an equally simple sprite rendering SWI would have been too 
high level as an OS service or too much effort to add. In fact, this 
functionality is all present in the Drawfile module. It would have 
made sense to expose it as a SWI.
