I'm not sure if you want to support both dev-server 5 and 6 at the same time, with 6 being the one that has plugin support, or if you'd rather introduce this in a new major version for dev-server 6.

[bjohansebas]

I think it's preferable to support dev-server 6 so it's easy to switch between versions, rather than releasing a new major version and making it more difficult to upgrade.
