Defining the core rules

[Joseph Paul]

And what I think I am groping towards here is the idea that there is so very little of BRP that is essential for there to be a game that everything else is optional because if you take it out it doesn't crash the game.

It might crash a setting such as CoC if you did not have SAN but that is just an example of an optional rule that doesn't affect the rest of the rules when it isn't present.

Triff's point is well taken. The defaults given will be what is supported so we all might need to sharpen our pencils to make those corrections to fit things into our own games. I wonder if it is easier to provide bare bones 'default only' stuff or go whole hog and use all of the options for describing an NPC/equipment/whatever and let the GM pare it down to what they want to work with. I think Runelords did that.
