New submission from chrysn:
The CoAP protocol (RFC 7252) registers the new URI schemes coap and coaps. They

uses_netloc lists in urllib.parse.

* Issue 18828: redis, also proposing to urljoin() arbitrary schemes
* Issue 15009: yelp

for that, please don't let the ideal solution get in the way of a practical
update of the uri scheme list.

I too would like to see this issue dealt with generically. I believe the last
time we discussed it the barrier was backward compatibility and which RFCs we
actually support :(. Fixing it generically will require a well thought out and
well researched

I'm also +1 to handling this generically and agree that a well thought out and
researched proposal would be required.
I did mention in #18228 (http://bugs.python.org/issue18828#msg238363) that I
think that a short term solution to this problem could be to
