This is a very good write-up.

Please make sure all of the above appears in the commit log message
somewhere.

If the function "handles everything for us", that's fine, but the
primary reason I am hesitant is because parse_connect_url() was
designed specifically not to have to worry about some protocols
(e.g. I think feeding it a "http://"; would fail, and more
importantly, its current callers want such a call to fail).  Also it
is meant to handle some non-protocols (e.g. scp style host:path that
does not follow <scheme>://...).

Also does it handle the "2222" case above?  I do not think
parse_connect_url() even calls get_host_and_port() to be able to
tell what "2222" means in these examples.
