>but it feels like it would be a massive headache for me to work out how to select and implement some harness for this and set it up for people

Switching to OpenCode or Pi harness is trivial for developers. So it certainly makes sense for those of us.

If it's problematic or not worth in your organization, then the switch doesn't make sense as you pointed out.

It could be worth it if the cost is lower or performance is better. It's a question of the risk of switching if we are not knowledgeable enough to do it properly. Maybe in time a product will appear that makes it very easy for regular workers to do this.
