You're right, probably the correct order for Configless must be:
* stop slurmctld
* edit slurm.conf etc.
* start slurmctld
* restart the slurmd nodes to pick up new slurm.conf

Less-Safe, but usually okay, procedure:
1. Change configs
2. Restart slurmctld
3. Restart all slurmd processes really quickly
Sure, I'd seen that: but it's not exactly ideal, is it?
Not ideal, but there are Slurm design reasons (node bitmaps) that
necessitate restarting slurmd's when nodes are added or removed.
Roll on dynamic node adding and removing...
Yes, see slide 37 in https://slurm.schedmd.com/SLUG21/Roadmap.pdf from the
