We do currently have plans to add support for each of these schedulers, and we have an open issue tracking the overall progress of this here. If you have a Github account you can subscribe to this issue (or any of the scheduler-specific issues) to receive updates on this as it progresses.
Currently our priority is adding Slurm support, and this should make its way into a Flight release soon. We will then look at adding support for further schedulers, and we will of course prioritise ones we have received more demand for.
Hope this helps and let me know if you have any further questions.
