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:
* I load bogus self-signed certs
* I have an http server masquerading as an https server
* I load an expired self-signed cert
It certainly makes sense for the default to be the most secure, but other use
cases must be preserved.
