I found https://yarchive.net/comp/linux/everything_is_file.html https://yarchive.net/comp/linux/everything_is_file.html a very compelling read today, on similar topics. Specifically, having a base set of abstractions that everything "speaks" is a huge boon that is often hard to articulate. Annoying, as the drawbacks and sheer number of edges is often much more easily described. TO that end, Emacs' "everything is open to everything else" works surprisingly well, once you get used to it. Especially so if you go with not introducing new primitives to makes things happen in the process. Even "async" is relatively easy once you get used to the sentinel approach. Can you imagine a better way? Almost certainly. I have yet to see one survive the test of so many contributors, though.
