Anyone with more complex cases like Wine can work with Wayland directly. Wayland protocols are pretty stable. If they care to support X too they'd need two paths. But something like freerdp for example managed to do it with SDL well enough. SDL of all projects actually did think about translating older ABIs to avoid breaking changes. I.e. there is SDL 1 over SDL 2 helper. It would be nice to see more of such efforts on Linux.
