I bumped into the same issue with aiocoap 0.3 and implemented essentially the same workaround.
However, when I look at the code in master, it seems that the multicast request method has been removed. Does that mean that the project is dropping multicast request support?

Multicast was removed because it didn't actually work -- but if it does for you, I'll have to re-evaluate that.
(The current state of multicast in the 0.4 pre-releases is that it works server-side, but client-side you can only do pseudo-anycast, meaning you send a request to a multicast address, but only receive the first response as "the" response).
I'll have a closer look at this (also to reinstate multicast -- how well does it work for you in 0.3? Do you reliably get all the expected answers?), but can't promise when exactly at the moment.

Thanks for continuing to maintain this project, I appreciate it!
Rather than what the OP did, I wrote asyncio.get_running_loop().run_until_complete(self.responses.finish())
but that amounts to the same thing. Doing that does get things going for me.
I'm not sure what you mean by 'reliably' - it's udp multicast after all, but on my small quiet network with a small number of servers, I'm able to see responses from all of my servers every time I make a multicast request.
I'll eventually need DTLS support, so I took a hack at trying to implement multicast support in master. I'll make up a pull request for that soon. I expect that I made a grievous error somewhere so a code review would be appreciated.
