Why should it?

That is *not* a good reason to make the argument mandatory.

That is a good reason to document why they should do so and
thus encourage them to do so.  Making such an argument
mandatory for that reason alone is quite misguided.

it was made.  Again, there is no good reason *not* to fix
this.
