Transportation balancing- ELytra

Elytras have quite obviously dominated the transportation scene making all other methods of transport irrevelant, killling creativity in railway building or ice boating as motivation to do so is removed. I  believe a suitable change would be to make it so that Mending is incompatible with the elytra. Unbreaking 3 can also be nerfed on it aswell or entirely removed. Durability for elytra would no longer go down as you fly but every time you rocket boost, and it would do so at a high rate. So for an elytra without unbreaking maybe it breaks every 200 or so rockets, and unbreaking 3 higher than that. You all already have a perfect repair system with phantom membranes, this adds a perfect trade off to this OP item, as To utilize it you would have to regularly kill phantoms or develop some sort of farm for IT. And even if OP farms are made it still require you to avoid  sleep to do so and sets a natural limit to how often you can rocket boost as you can only acquire phantom membranes on nightfall. adjusting how much one phantom membrane repairs the wings by and XP needed to anvil. Every other form of transport- iceboats, railways, horses, have major downsides such ass Build time and farming to get ice and craft tracks, Yet the elytra simply has none, as with mending and how cheap rockets are all you need is a creeper and XP farm. A buff to railways would also be nice like that one experimental speed change just toned down.the craft cost makes the powered rails fair to be fast.
