Unless you want to discuss why you needed a separate /boot partition. Yes, I would like to know that. It's a common safety mechanism so that '/boot' can be excluded from any partition/file system optimization standard maintenance routines that reduce file fragmentation. While specific files can be marked for non-optimization, it seems having a separate "boot" partition is a small price to pay for having a file system that can remain untouched during normal operations.
Who knows, it might be a good candidate to use for an emergency recovery partition (like what might be contained on a separate DVD) so that for most recoveries, scrambling for a DVD compatible with your latest OS would be unnecessary.
Googling, it seems to be about reducing complexity; https://superuser.com/questions/522971/is-a-boot-partition-always-necessary I think it's safer to keep /boot partition separate to avoid overwriting the bootloader by mistake. If I'm not mistaken the boot loader should be in the first cylinders of the disk to make sure the boot process will work properly as BIOS always load the first Bytes from the disk assuming there is a code that could handle further control and is able to load the operating system It can also reduce risk, by having that file system to RO without affecting the rest of the RootFS. or put it offline. The put it back and to RW when updating the kernel. One of the problems with the BtrFS is that it wants on file system for everything, even if the subvolume mechanism sort-of/almost looks like partitioning. That means you have one filesystem POF. There are many good reasons to have partitions like /home and /{usr/}local that you can put off-line when upgrading. And as I've pointed out before, if you subscribe to the idea of 'hard copy' backup to DVD, having file system partitioned to 5Gs fits that. -- “Reality is so complex, we must move away from dogma, whether it’s conspiracy theories or free-market,” -- James Glattfelder. http://jth.ch/jbg
