Okay so I've got it all figured out I think. I talked with some more long-time EQEmu geniuses to get to the bottom of this since it really confused me and found out some things.

Many spells in classic had hardcoded elements, over time the hardcoding in these spells was removed and made into actual spell data which you could see, (one example of this that they mentioned I won't mention because my guild's top raid leader will literally kill me if I bug report it since it would be a huge sweeping nerf to literally every single spell of his class, sorry Nilbog but you can't catch 'em all, they're already mad enough about the potential abashi nerf) so in actuality the "change" of Silver Breath and Abolish Enchantment from a normal Cancel Magic component to a Cancel Magic - Beneficial Only component was actually just the devs cleaning the spell up and thus making the spell data seen in the spell file reflect the actual truth as it always had been since the spell's inception.
