Which is why HTTP/2 has padding, and TLS 1.3 will probably have it.

The IETF isn't "encrypt everything" but rather "pervasive monitoring is an attack," with the knowledge that protection of meta-data (DNS, padding, timing) is important.  There's no guarantee we'll get it right, or even if it's possible, but they're trying.
