Again though, that's not actually computationally expensive. It's just hard to get right & maintain, with few do-all open-source offerings ready to stand in. It's not like having 10x the computing resources at hand would highly motivate someone to bring it onboard: it's a difficult thing to manage well, but not actually computationally expensive to do so.
