BTRFS: does defragmentation break reflinks, snapshots, dedup?

Hello

The documentation of the btrfs filesystem defragment subcommand mentions unintended effects of defragmentation and refers to a slew of Linux kernel versions, possibly up to the latest? Does anyone have experience with defragmentation?

Elsewhere in the documentation clarifies that reflinks between subvolumes are broken by defragmentation. This should not cause significant problems in the common configuration with / and /home subvolumes, which most likely don't share a lot of data, correct?

Thanks for your help
