I have my main distro installed on one nvme, and have 4 50Gib partitions set aside on another for playing around with up to 4 other distros. No microslop. No other distro that I have tried had an issue with that set up.
I will check it out again some day on my old (pre nvme) pc instead. Much easier with 2.5" drives






Doesn’t sound worth it for me, I always want a back up distro on a different drive, just in case I stuff anything up, and I do like to occasionally install other distros just to check them out. The majority play well together.
