The middleware is fairly basic python script (mostly)
Any operator could easily add it in. Which sounds to be ok. Only a problem if people are allowed the choice to use it outside of that operators website/dapp
Already found in many front-end setting
If I understand correctly, this is what you don't like. If any front-end offers a selection, then the selection should only allow options that meet a particular criteria. Like if deathwing.blog wants to let people choose ecency.com's api server, then there must be some certification that ecency.com's api server meets the requirements
That's probably the opposite direction tho, isn't it? Ideally, rather than have a central authority dictating what software the people of the world may or may not run on their servers, you have a group that represents your interests and certifies what is compliant and what isn't. Maybe they have a front-end that only lists certified APIs and also promotes those api's for use on other sites
