The ideal theory is that since they are dogfooding it, their devs will make sure it’s ergonomic and useful. Whether that works or not, well… I think history mostly speaks for itself. 
Story of 90% of all business decisions in this civilization… since forever really.
If memory serves, a number of people said that the Linux kernel just does not lend itself to fully preemptive scheduling as much as we like it to? Sorry if spouting a falsehood here, I might remember wrongly. I heard people say that some of the *BSD OS-es are doing this better and are a better target for experimenting with directly-kernel-backed features when aiming for real-time low-latency preemptively-scheduled software. I’d be surprised if this is still the case and if Linux still lags behind in this department but oh well, its kernel development is a whole different beast and usually extremely conservative…
If you have any links to discussions I’d be curious to go check them out.
