I don't know what your issue is apart from maybe being a Synology shill.

Features change in software all the time.

What's so outlandish about someone getting a new unit, it upgrades the software automatically on first run, and then the BTFRS filesystem is available to them use for the array.

You'd either not think twice about it or thank Synology for opening up the new feature for these lower end units.

Taking the feature away like this is the absolute trashiest behaviour.
