Possible to add _start_tls_compatible attribute to TCPTransport?

[rahuliyer95]

• uvloop version: 0.19.0
• Python version: 3.10.7
• Platform: Linux
• Can you reproduce the bug with PYTHONASYNCIODEBUG in env?: Yes
• Does uvloop behave differently from vanilla asyncio? How?: Yes

aiohttp (3.9.1) keeps warning (falsely) about ¹

RuntimeWarning: An HTTPS request is being sent through an HTTPS proxy. This support for TLS in TLS is known to be disabled in the stdlib asyncio (Python <3.11). This is why you'll probably see an error in the log below.

It throws this warning because it's not able to find _start_tls_compatible property on the TCPTransport object (https://github.com/aio-libs/aiohttp/blob/v3.9.1/aiohttp/connector.py#L1054). The same property is present when asyncio is used which provides SelectorSocketTransport as the underlying transport. Is it possible to provide the _start_tls_compatible attribute on the TCPTransport which can help us avoid this warning?
