Command-based access to legacy textures/features

Hi Mojang, I'd love an official command-based way to get legacy textures/features, similar to custom player heads. Texture/feature changes can ruin old builds, and resource packs are global and limited. With the data-driven model system, you could bundle legacy models into the client and let commands reference them, e.g.: /give @s minecraft:diamond_sword[minecraft:item_model="minecraft:legacy_diamond_sword"] No resource pack needed. It would help builders preserve old creations and reduce community splits. Storage cost is tiny. Please consider it. Thanks.
