That's not simple. Erlang 18 has ABI-incompatibilities with Erlang R16
(NIF/Drivers API, obsolete functions like erlang:now(), different types like
dict vs. dict:dicts, etc). I strongly support that but currently it would
violate EPEL packaging rules too much.

I agree this challenges Fedora/EPEL package updates policy.
One solution mentioned in related BZ#1309525 would be to have Red Hat Software
Collections (SCL) to take care of it. Since Erlang is not part of SCL yet, it'd
have to be added/accepted first.
Some thoughts here:
Programming languages have regular and important updates. EPEL, because of RHEL
long life cycle cannot take advantage of those new releases.
Fedora has only the latest RPM available, which might make sense when targeting
only cutting edge environments. But if EPEL could instead follow RHEL channels
approach and keep all RPM released versions then that would not be an issue
because those who need a previous version (Erlang 16, or Erlang 17) could still
get it and the latest RPM version would be the latest but stable version
(Erlang 18)

Erlang 17 and Erlang 18 as currently packaged would conflict. We would need
retool Erlang packaging to use 'alternatives', and alternatives isn't
actually
that good (i.e.: systems with two versions of Java have a hard time using both,
if you need them for example to support different programs/daemons running at
the same time).
These issues are exactly why SCL exists... IMO SCL is a saner path, but again
quite a bit of work.
I am happy to lend a hand with an SCL Erlang 18 or a COPR repo. As I mentioned
in BZ#1309525 I have a very crude repo with Erlang 18 and Elixir 1.2.2 for
EL7.

That's not simple. Erlang 18 has ABI-incompatibilities with Erlang R16
(NIF/Drivers API, obsolete functions like erlang:now(), different types like
dict vs. dict:dicts, etc). I strongly support that but currently it would
violate EPEL packaging rules too much.
What about erlang 17 ? Does it have ABI incompatibilities too ?
Fwiw, I'm currently struggling with ejabberd for EL7. I have a working cluster,
but I'm stuck with ejabberd 15.07 which is the latest version supporting erlang
16. erlang 17 would allow to get ejabberd 17.04 and probably future versions to
run. I'd be willing to maintain ejabberd in EPEL 7, but I'd rather leave the
erlang stack to more skilled buddies.
