I don't find it hard to write asyncio code but I find it hard to generically interface with other people's asyncio code and that is lacking basic support like a context object or logical call contexts or just the lack of agreed upon usage patterns.

It does not help that asyncio evolves in the stdlib and changes with every major Python version. It might be less of an issue if this was pip installable I suppose. Right now writing utility code for asyncio is targeting many things.
