I propose to change the fun(pointer + 0) logic with fun(pointer, 0).
We still maintain the sanity checks and we can optimize the code to
generate not worse code than before. We can pass the "0" argument only
with DIAGNOSTIC or DEBUG kernel.

I don't think this is a good approach -- it requires modifying code
further and further away from the relevant part.
But let's step back a moment.
So far,
