For some items I see the addition as a possible compliment to staking to a point that the amount of staking could be reduced to remove less anodizing to extend component life if was to be disassembled later and reused.
The proper staking for a castle nut will remove the protective anodizing layer from the parts. The reality is that most of these parts will never be removed and nobody would notice.
Less mechanical resistance to movement VS a bonding agent could help some things, but I wouldn't omit at least some mechanical tension.
