Anyway, with the amount of testing and verification we do on our product, desktop Linux is impractical. And yet, there are many open source projects have the scale of a file synchronization tool or larger, that manage to work fine (and run a large battery of tests) across different Linux distributions, BSDs, and macOS. I don't think it is impractical, it is probably just not a good business case. (I don't necessarily agree, I think Linux users will typically send more fine-grained and useful bug reports and might help you shake out bugs more quickly.)
