Is there a reason why armor and weapons in Collections cannot be reacquired in 2025?

Has Bungie ever given us a reason as to why this is? Where's the harm in letting us pull weapons with static rolls, or armor with 46 rolls? What's the point of having a glorified checklist?

It's minor, and not a priority, but I just never understood why after our armor was changed to mod slots instead of random perks why the Collections wasn't updated. Personally, I just wish I could pull out old guns from Forsaken to play around with from time to time. Hell, make every static weapon have some stupid perk that doesn't work on the gun at all or something. Does anyone else feel like Collections could be better?
