Exciting to see this proposal and the potential for using web technologies for some interaction built on top of a messaging environment.
In some ways, this sounds similar to MiniApps, a class of web-based service that has growing popularity especially in China. Has anyone compared the relevant capabilities and distribution mechanisms?
Would there be an interest in standardizing this tech so that it could be implement in messaging outside of just Delta Chat? That process might also be a time to consider the security and privacy implications, and to see where we can re-use technologies that exist for packaging and securing web content that isn’t transmitted through live browser navigations.
