Some legit sites with proper

bundle the intermediates, and I've told their devs about it, but all I

will surprise people greatly. But I'd still rather the default be
True.


I'm happy if the "will cease to work" clause only says "some sites with
broken security configurations may stop working" with a clear explanation
that it is *their* fault, not Python's. I'd also expect that the same sites
would fail in browsers - if not, we should also be able to make them work
(or face cries of "well, Internet Explorer/Firefox doesn't have a problem
with my site, why does Python?").

Keep in mind that not every HTTPS service is a Web site that is meant
to be readable with a browser. Some are Web services, possibly internal,
possibly without a domain name (and, therefore, probably a non-matching
certificate subject name).

They should need to explicitly opt in to disabling the checks that allow that to work.

Obviously, which means compatibility is broken with existing code.

Antoine.

Yes in that case compat will be broken and they'll need to either specify a cert that can be used to validate the connection or disable the protection. I think it's very surprising for people that they need to *enable* secure mode when most tools have that on by default. It's handing users a security foot gun, and like most things security related "broken" is silent until it's too late.
