Your examples are all correct.

The major change between HTTP/2.0 and HTTP/1.1 is that the host header
is now optional.  It can be omitted if the absolute form (i.e.,
:authority) is used.  In fact, we obliquely encourage implementations
to omit host.

This places a constraint on an implementation that converts from 2.0
to 1.1; if host is not set it has to copy it from :authority.

But nothing has really changed other than that, host -> host and URL
authority -> :authority.
