Reasoning

Home Assistant works with asyncio to be efficient when handling tasks. To avoid switching context between the asyncio event loop and other threads, which is costly performance wise, ideally, your library should also use asyncio.

This results not only in a more efficient system but the code is also more neat.

More information on how to create a library can be found in the documentation.
