Once everything gets rebalanced though, I don't think I'd be missing out on any

The default nodesize/leafsize is 16KB since btrfs-progs v3.12. This
isn't changed with a balance. The difference between the previous
default 4KB, and 16KB is performance and small file efficiency.
Ah, now it's coming back to me. The last major gyration I had on this
filesystem (and the ultimate trigger for my original issue) was juggling
everything around so that I could reformat for the 16kB node size.
Incidentally, is there a way for someone to tell what the node size
currently is for a btrfs filesystem? I never noticed that info printed
anywhere from any of the btrfs utilities.
In case anyone's wondering, I did balance the system chunks on my
filesystem and "btrfs fi df" now looks normal. So thanks to all for the
hints and advice.
