I've really been enjoying the new weapon attachment system in arma 3 as it makes everything a whole lot easier compared to arma 2, but I thought that it was a little unfortunate that community made addons can't be placed on the stock arma 3 weapons so, hopefully someone out there agrees with me.

+1. There was an idea floating around of having magazine/weapon compatibility based on "interfaces" rather than a direct list of compatible magazines. Same idea may be applied to the attachments - example of interface may be some classes like "RIS_rail_up","RIS_rail_side", "RIS_rail_bottom" which are referenced in both weapon class (describing which rails it has) and in attachment (describing where it can be attached).
