I like Jiri's idea. Why not deliver the distribution without a certificate
but add documentation and tooling (scripts or code) to easily install a
certificate from letsencrypt.org? It's the cleanest solution since it will
avoid bundling a self-signed certificate. The main issue I have with
self-signed certificates is that users will most likely not change it,
which is a bigger issue than using unsecured connections.

to issue the "star" certificate, but for the dev purposes all we need is
the cert for the localhost, right?
As for the production, we may provide some script + docs how to generate
the cert in the https://letsencrypt.org
