Singular hypercorn before/after hook

[sky-cake]

Does hypercorn have before/on_start and after/on_end async hooks that don't get called for each worker spawned? If not, how do you suggest achieving this?

Here is a POC,

from asyncio import sleep
from quart import Quart

app = Quart(__name__)

@app.route('/')
async def hello():
    return 'hello'

@app.before_serving
async def on_start():
    await sleep(0.01)
    print('Wish to only print once, on start')

@app.after_serving
async def on_end():
    await sleep(0.01)
    print('Wish to only print once, on end')
