Hi,
I was recently wondering about this again, and found that now there is a PR for wlroots: https://gitlab.freedesktop.org/wlroots/wlroots/-/merge_requests/5115/diffs
For now, I created a rebased and updated version of this PR here: https://github.com/dkondor/wayfire/tree/workspaces3 (it works if cherry picking the wlroots PR on version 0.19, as e.g. here: https://github.com/dkondor/wlroots/tree/ext-workspace-backport)

Hi! Now that Wayfire master is on wlroots 0.20 with ext-workspace-v1 support, do you think there’s a chance this PR could be merged?

I don't plan to work on this feature, as I am using IPC for everything these days. I know @dkondor has some rebased patches, which might be acceptable upstream. Note that Wayfire's workspace model has adapted a bit since this PR was started - we now have workspace sets, which shouldn't be hard to represent in the ext-workspace protocol, but may need additional work as well.
