Flags and banners for mobs, vehicles, and beds

I propose expanding the functionality of banners and making them more useful than just decorative blocks. Banners could be placed on certain mobs and objects, such as horses, camels, and other suitable mobs, to represent ownership, teams, or simply for decoration. On some animals, a banner could be worn on the back, similar to how Pillagers carry banners. Players could also wear a banner on their back using a separate slot, so it would not take up an armor slot. This would be especially useful on servers for identifying teams, factions, and players. On boats and minecarts, a banner could be placed at the front or back without affecting their speed or properties. Banners could be placed on shields, allowing players to use their custom patterns as part of their equipment. Beds could have more customization options: a banner could be placed at the front or back of a bed, and its pattern could be applied directly to the bedspread using a Loom. Players could also change the color and pattern of pillows independently from the bed color. The number of possible banner pattern combinations could be increased as well, allowing players to create more complex symbols, coats of arms, and decorative designs. All of these features would allow banners to be used to create custom coats of arms, mark territories and teams, and decorate vehicles, mobs, beds, and builds. These features would be especially useful for medieval builds, castles, villages, servers, and adventure maps.
