This is also the fault of shit-tastic middleware boxes which block any protocol they don't understand-- because, hey, it's "more secure" to default-fail, right?-- so every new type of application traffic until the end of time has to be tunneled over HTTP if it wants to work over the real Internet.

If the intent is to secure something then failing-open will indeed be at odds with that goal. I suspect you’re not implying otherwise, but rather expressing frustration that such providers simply can’t be bothered to put in the work and use security as an excuse.
