Alright. All in due time. It is not that I have gazillions of such large 
files laying around or even the amount of storage capacity available. I 
intend to format an external 4TB NVME SSD with encrypted BCacheFS. And for 
testing copy over 1 TB of data from an external 2TB NVME SSD to it and see 
how that goes.

I am happy that BCacheFS went into the mainline kernel and I rather see 
things done right than fast.

Have a Happy New Year.

Best,
