In the 2.3.40 patch, I see the following:

It looks like a similar change is in the 2.2.1 patch, but I missed it
amidst the clutter caused by the code reformatting. The minimized
version I posted does *not* include this change.
So what do these changes do? What problem are they fixing?

The most foolish mistake we could possibly make would be to permit
the conquered Eastern peoples to have arms. History teaches that all
conquerors who have allowed their subject races to carry arms have
prepared their own downfall by doing so.
