Details:

Linux 4.14 supports Zstd as compression algorithm for btrfs. Unfortunately
GRUB doesn't support this configuration, meaning that is not possible to have
a Zstd compressed root without a separate /boot partition.

As GRUB supports the other btrfs compression algorithms, it would really make
sense to support Zstd too.
