Maintaining multiple SKUs with major differences is quite expensive and time consuming, plus confusing for the customer on a global Internet trying to look things up. I expect that this would make at least some manufacturers ship these to other countries, so we would have some options.
This is the most important takeaway. There’s a lot of people whining about Wayland, but Wayland devs are currently the only people actually willing to put in the work. Nobody wants to work on X and nobody wants to make an alternative to Wayland, so why do we keep wasting time on this topic?
