Right now it only starts as X11 client and Wayland client, so I have no choice but $ cage wio
But it doesn't on my Lenovo Ideapad 100-15IBD 80QQ, it simply takes away input without producing any output, but if I'm lucky it crashes and I don't reboot my laptop.
It could be that due to wlroots changes, the compositor must now explicitely enable and commit to an output when running from the VT. I submitted a patch to add this, which now let me start wio from the TTY directly. See https://lists.sr.ht/~sircmpwn/wio/patches/15055
