"""HomeAssistant specific aiohttp Site.
Vanilla TCPSite accepts only str as host. However, the underlying asyncio's
create_server() implementation does take a list of strings to bind to multiple
host IP's. To support multiple server_host entries (e.g. to enable dual-stack
explicitly), we would like to pass an array of strings. Bring our own
implementation inspired by TCPSite.
Custom TCPSite can be dropped when https://github.com/aio-libs/aiohttp/pull/4894
is merged.
