I actually agree with the general sentiment, but,

Then you have to fix all the code which has assumed such, breaking
previously-correct code. bcrl (IIRC) was the one who told me about
kfree doing the NULL check; likewise akpm for brelse. So people are
using these things.

Do you really want to audit every single kfree and brelse to implement
this change?
