Sadly too many people have that view because they don't see the problems when they are coding and testing so they think they don't exist. Mime types matter for security, for maximum interoperability and for enabling serendipitously-discovered use-cases.

Sadly the approach you take on this has the opposite effect to what you aspire to. Yes, rigidness causes too many problems, but no one is saying to be rigid on the client end. If you were to instead consider The Robustness Principle a.k.a. Postel's law "Be conservative in what you do; be liberal in what you accept from others" then you'd see that it is better for the server to be strict which then allows the client to be strict or not-strict, whatever it likes. Rigidity only causes problems with the client is rigid too.
I do understand the instinct to rebel from authority, I have it myself, but I hope you can see how arguing for chaos on the response end of the HTTP standards is counter-productive.
