It's an interesting point.
Philosophically the more one thinks about swept wing high subsonic airliners the more one realises they are designed to climb benignly, cruise in a stable configuration and descend gently.
Big, vulnerable ocean liners of the sky that are pretty much optimised to point directly into a high mach airflow, and stay there.
A great over simplication of course, but makes you realise how perilous things get very quickly when they are outside that envelope.
