The package does not seem to be unusable, I see for example the averell
package which depends on erlang-cowboy and does not have any open bug.

The version of the cowboy application is 2.0.0-pre.1, thus the version
of the package is correct.

Debian follows the convention of bumping binary package names for major
shared library ABI changes but this practice does not cover Erlang
modules thus bumping the binary package name is not warranted here.

Debian also provides multiple versions of gcc for example in separate
source packages but gcc is one of the most central and widely used
packages but it is not the established practice for Erlang packages and
I don't think the case for erlang-cowboy is strong enough to start
shipping two variants.

This pre-release was uploaded on 2015-05-05 and we are too deep in the
freeze to either revert to 1.x or upload a new pre-release thus most
likely Stretch will be released with the current version.
After the release I  will update the package to latest 2.x pre-release
and will stay with stable updates in unstable.

If you need a packaged erlang-cowboy for Stretch you can ask for
backporting it to stretch-backports after the release.

Cheers,
Balint
