Updates on responsive images in posts?

Kevin did a pretty good job of answering that question in the thread you linked to

The reason srcset output hasn’t been implemented for content images yet is due to problems with the current design where only images sizes specified in the theme can be generated to avoid opening up DoS attacks. Content is static so if you change theme or adjust the allowed image sizes to cater for a new design then you may end up with image sizes referenced in your content that can no longer be dynamically generated.

We need to come up with an alternative method for specifying generally allowed image sizes, then a plan for how old content could be migrated to use dynamic image sizes (if that’s possible). There also needs to be considerations made for how the new feature would work inside markdown cards, again if that’s possible, it may need to be limited to image cards.

It’s something the core team is thinking about but we want to make sure the implementation is correct this time
