The reasoning here is the same as for hash randomization. There are cases where you want to test your application using self-signed certificates which don't validate against the system CA root list.

In those cases, you do know what you're doing. The test would fail otherwise and the reason is not a bug in your code, it's just the fact that the environment you're running it in is a test environment.

Exactly. I have test cases where I have to load up a self-signed cert via .load_cert_chain() and in the good-path tests, I expect to make successful https connections. I also have test cases that expect to fail when:

It certainly makes sense for the default to be the most secure, but other use cases must be preserved.
