Supporting a language fully on a variety of non-Apple platforms is a massive undertaking. Even assuming for the sake of argument, unlimited funding, there's still the issue of finding the right talent, as well as expending limited managerial bandwidth for oversight & prioritization. I think the Linux support that already exists is an awesome start. But the only realistic way to see more from Apple on this is if they themselves start to deploy critical Swift web-services on their own backend infra. (I'm assuming here that they run Linux systems somewhere in their stack.) That will give them the incentive to take it to the next level. Until then it's largely left to the community to find the energy and time to do this.
