Although the move to the cedar stack introduced a lot of complexity, Heroku's flexibility is really starting to shine through - I've seen work on a smalltalk buildpack as well.
Long-term this trend is only going to accelerate, where we can assume an app-receptacle (lxc-containers, heroku's 'app', etc.) is setup properly out of the box. There are almost no downsides to this when executed well on the provider's side, and infinite upsides.
I wonder if we'll start seeing higher level buildpacks. Not just for languages, but frameworks sitting on top of languages which are optimized in some way, and take a much simplified DSL / templating & let you avoid building all the pipes as well.
