Or the use case of a preempt kernel on said arch has never been a request.
Just because it was available doesn't necessarily mean it's required.

Please, let's not jump to threats of removal just to get a feature in.
Simply ask first. I didn't see anyone reaching out to the maintainers
asking for this as it will be needed for a new feature that will likely
make maintaining said arch easier.

Everything is still in brainstorming mode.
