Have you tried waypipe? Does it not fit your use case?
Last time I tested this, which was a few years ago, it worked just fine. But to be fair, this is not part of my workflow, just something I was testing out of curiosity.
If it doesn't do what you need for whatever reason, then I understand, but it just not true at all that the Wayland ecosystem has not been addressing these use cases.
I did try waypipe, but unfortunately there was both a significant memory cost and network overhead that does not exist with ssh -x.
To be fair I am using it in a very niche and limited way, but it still sucks to see it get pushed out in an ecosystem that is supposed to be all about maintaining support for niche systems.
Not to go off on a tangent, but over the last decade or so I feel like Windows has been better about making sure things keep working than modern distros have.
