Wither Mining Tunnel

I saw some minecraft videos that were talking about using beds in the nether and I was like, "nah imma just summon a wither and let it dig for me". I dug a tunnel about 1500 or so blocks in one directions, spawned a wither at the end and let it follow me all the way back. Sure I have to contend with lava flows from lakes above and stuff but eh, it beats laying down a ton of beds and shearing tons of sheep. You just have to kite a murderous Wither for a thousand blocks or so. This is Minecraft Bedrock Edition on my PS5 Pro.
