Yes, well, it would be nice if rebar could introduce some good support for conditional dependencies.

For example, you don’t need:
- afunix, if you don’t plan to use the collectd reporter
- bear and folsom, if you don’t want to use folsom
- exo, if you don’t use the graphite reporter
- netlink, if you don’t plan to use the experimental netlink probe

edown and meck are only used for docs and testing.

That’s of course the problem with trying to make a generic abstraction layer that’s still complete enough and broad enough to attract a community: you eventually have to tie yourself to some libraries (like lager), and simply accept that it will not be the preferred flavor for everyone.
