Do the Large Boost Versions of the Standard File System Really Exist?

i was thinking about azio and files tis, don't know, the sepus plus 23 networking or whatever. And boost file system is what led to standard file system. i'm looking at how these things are not staying stagnant, right? These are moving targets. They're growing and developing in a way that the standard library ones just simply can't. I think there's value to having it there especialy as we concee that they're able to update it at thi speed"
