Yes, but 3DES is from 1978 and SSL (as anything other than a Netscape-only feature) is from 1996, and IPsec is from even later, so those protocols could have been defined without known-weak algorithms.

And TLS 1.2 introducing MD5-based signatures in 2008 where previously there was only SHA-1 concatenated with MD5?  That’s just weird.
