Hey, I'd be interest to have this merged, is there anything blocking this to be merged ? Thank you !

I tried

from fastapi import FastAPI, Form, Depends, UploadFile
from pydantic import BaseModel

app = FastAPI()


class SimpleModel(BaseModel):
    no: int = Form(...)
    nm: str = Form(...)
    f: UploadFile = Form(...)


@app.post("/form")
async def form_post(form_data: SimpleModel = Depends()):
    fp = await form_data.f.read()
    print(fp)

It works with current (0.86) version. Is this PR still needed?
