Is still around, at least for some values of "around".

Elvis, at its latest release (2.2.0) is a required part of Slackware, part of the A (essential system) package series. I have it installed on my system, alongside Plasma 6.7 and kernel 7.1.

I suppose, but you can only install it via the AUR or nixpkgs on linux, and 2 out of the 4 BSDs no longer have ports. Sure, you can compile from source but when it's that old I consider such a state effectively no longer around
