The only problem is the ability to export/migrate is entirely in the hands of the third party platform. Rate limits, controlled APIs, bot restrictions and all the rest is why this process is so difficult. But for sure it would be awesome if we could do that. Although you have a hosting problem there as well, but I think there are solutions to that and I know many people (myself included) who are trying to solve that one. 

 I’m watching and happy to alpha/beta test any tools you find worth trying in the wild. 

 I hope to have something very exciting to share soon. Although it may remain to a smaller private group for a while for testing. But I’ve made a hefty investment in hopefully solving some of the most important problems toward this. 🫡✊🏻
