I'm not sure I said that there are show stoppers for not using container images. What I said is its not how our cloud platform works. In fact a cloud site is actually implemented quite differently to that of a traditionally hosted platform
Its worth noting, that when looking at feedback and suggestions, there has to be a value add for us to make such changes. In the case of this, it would be quite a large change to our current methods of deployment, for quite little payback. This isnt to say that a decision has been made not to (that would not be mine to make). I'm just saying its not quite as simple as saying "This hasn't been implemented because there are showstopping issues that stop us from doing so". Most suggestions are perfectly doable, its just most dont make sense to do within the scope and vision of our platform.
