I understand the appeal of using "existing technology" (i.e. Wayland) to accomplish something when it appears that it will make it much easier.

But if GTK is still at least nominally cross-platform, then surely the place to start is a higher level abstraction of the transport system, and then later to bolt wayland onto that design "under the hood", rather than starting with Wayland and then shrugging one's hands and saying "do something like Wayland on other platforms"?

I don't see how anything I've said could be used to imply that GTK is, nominally or concretely, not cross-platform anymore.

What is being discussed here is the possibility of using Wayland as the implementation to communicate privately between the preview plugin process and the main process, without a Wayland requirement for the session the processes live in.

I'm arguing that as long as the Wayland libraries can be built on the platforms we care about and a suitable way of sharing a buffer exists, even if not extremely optimized, we can possibly get away without the abstraction you're talking about.
