Flannel relies on etcd. I had stability issues with v1 of etcd which meant flannel couldn't route packets. Since then, the idea of using an immature SDN atop an immature distributed key value store fills me with dread.

Interesting. But that's an old version. Calico [1] uses etcd as well (version 2.0.5 I think?) and I've never had any problems so far...

You can of course use etcd with weave... indeed weave can be run with no dependencies, so it may make sense as a way to bootstrap etcd ;-)

I gave up on SDNs and fell back to doing what anyone does without an SDN: published ports to the host interface and advertised the endpoint <host_ip>:<container_port> to etcd. Note this wasn't with kubernetes but with a similar system. Still reliant on etcd, which I wasn't happy with, but one less cog to go wrong.
