Awesome! Really awesome!

I am running BTRFS on a ThinkPad T520 since at least 2014. After all 
these initial free space related issues went away with linux 4.5 or 4.6 
I had no issues with it anymore. In part I use BTRFS RAID 1 with an 
mSATA SSD on the laptop and it recovered from what I believe had been 
power loss related errors on the mSATA SSD twice already. Of course that 
is not anywhere near the dimension of errors the filesystem you have 

I use it on my backup drives and I use it on my server VMs.

It works for me.
