Had really good conversations in Wednesday’s dev chat and continued in today’s office hours. Seems like we’ve got a really good direction. All the UI User interface will be available all the time and theme support for individual formats will shift to serving as a flag for whether or not the theme handles format-specific data for display. If a format is not explicitly supported by the theme, there should be simple, semantic fallback output that can be hooked on to the_content. This allows the admin (and super admin) UI to stay consistent and able to offer data fields that don’t just disappear into nothingness, and themes can actually support post formats with just styling rather than handling format-specific data themselves.
Also, user testing was done with core as-is, and I’ve got videos to watch and analyze for post formats using Crowd Favorite’s UI and fallback code. These are extremely revealing and are really helping us identify pain points as well as setting a baseline for measuring any improvements we hope to make.
