sync_to_async tasks seems like something that's generally useful, and in-
line with the create_task and TaskGroup API. So, that's a useful step

I tested the updated asgiref with Django signals using my branch
{{{
pip install git+https://github.com/Arfey/asgiref.git@feat/added-custom-
context-parameter-for-sync-to-async#egg=asgiref
}}}
Everything works correctly:
{{{
./runtests.py signals
Testing against Django installed in ... with up to 10 processes
Found 28 test(s).
............................
----------------------------------------------------------------------
Ran 28 tests in 0.333s
