why inject() must be called synchronously ?

inject api

core/packages/runtime-core/src/apiInject.ts

Line 48 in 8dcb6c7

const instance = currentInstance || currentRenderingInstance

synchronously call will ensure the instance is properly.

I have read apiInject.ts; I would appreciate it if you could provide something about how to get the instance at run time. I still don't understand why I cannot get the instance by calling inject asynchronously.
