Any Filesystems in Linux Support Versioning?

When they talk about versioning they really are talking about something that *I think* would involve having apps that support versioning. For example in OpenVMS, if you use the text editor "EDT" and edit a text file:
1. The original file is MYLIST.TXT with a version of ;1
2. After you edit it, the original file is renamed from MYLIST.TXT;1 to MYLIST.TXT;2 and the newer file is called MYLIST.TXT;1
3. If you edit it again, then it the original becomes MYLIST.TXT;3, the second version is MYLIST.TXT;2 and the latest edit is MYLIST.TXT;1
This continues on for as long as you have files around and I believe it's configurable to limit how many versions back you retain. So this leads me to wonder if this is even possible on any Linux filesystem.
I'm aware that Emacs can produce versions of files with a configurable limit as well. But wouldn't it be nice if all apps could do it? Even nicer if the filesystem really handled it in a transparent way... AND if the versioning was reversed compared to VMS so that the latest is the highest number with the latest version having the ability to be referenced without needing to append the version number. VMS actually works like that regarding the latest version, you don't need to append the version number to the file name unless you want an older version. So, is there anything like this out there for Linux? Or is this likely to be a dead issue?
