Of course, it supports remote filesystems (NFS, Windows network shares, etc..), as these are just files, you can also run Sublime Text on a remote desktop or X server, and there as plugins for things like ssh-based synchronization, so its not that you can't do it.
But what it doesn't have and that VSCode and Zed have is the ability to edit files on a remote server with only an ssh connection, by running the GUI part on one machine and the file I/O part on the other.
Even though Sublime Text is my primary editor and I have no intention to change, it is still something I miss. It is one of the reasons I sometimes switch to VSCode (which is a good reminder of how slow VSCode is compared to ST).
If you mean git repos, Sublime Text itself only has minimal git support, but it integrates well with Sublime Merge, which, of course, supports remotes. I don't use Sublime Merge though, it is probably very good, but I never took the time to learn it, I do most of my git work on the command line.
