Not enough free space in your root btrfs? Consider your system trashed

Last week I've experienced a catastrophic failure after a system upgrade which led me to rolling back my root btrfs partition.
I'm used to this kind of things because every couple of years some mirror occasionally gets out of sync and if you're unlucky enough you end up with mismatched system libraries and the occasional hiccup. Not a big deal when you have snapshots.
After a few days I've tried to upgrade again and the same happened, which led me to initially file a bug (https://bugs.archlinux.org/task/78895) and soon thereafter realize that despite having a couple of GBs of free space (sudo btrfs filesystem usage / | grep Free) those might not be enough for the upgrade.
This led me thinking whether this could be somehow avoided or at least mitigated for those using cow filesystems.
