Typically, if something is relevant to the design choice or purpose of something, it's relayed or can be inquired about. As to commenting on day-to-day design stuff, that's not something Community would do because we're literally a different department that has other tasks/functions.
Put a different way, I'm employed 40 hours a week (lol, dare to dream <3, wee 15 hour day today so far~) doing Community related tasks. My personal area is Forums, though I take part in other tasks and have personal initiatives as well (such as the Customer Support Ticket awareness push to address behavioral issues). There's no reason for Community to be keeping track of Design-related stuff in a minutiae-sense because the Design teams are literally employed to do those things. We each have our role/function.
There has been a large increase in information being put out via DevBlogs and the new Roadmap (which will likely have an update at some point). We've been more transparent in general, and we've given specific information such as Container Mechanics and Contents.
I'm guessing from your question you are more asking for like, direct internal data as though looking to peer-review it. That level of data-sharing is not something that should be expected as a general ask. World of Warships is a highly complex game and is our intellectual property. Extensive amounts of data and internal process is similar in concept to the secret recipe for Coca-Cola, so there is a reasonable limit that should be expected in terms of what information we put out. Further, what information we put out has to be reviewed to be clear enough as to be understandable and avoid miscommunication as best as possible.
