The primary one I recall was that each mounted filesystem would have a corresponding kernel thread doing about 20 wakeups per second. This was not really good for battery life and power consumption in general. Last I checked (which was 2016 or so) those wakeups were slated to be around for a while longer. https://www.spinics.net/lists/xfs/msg40210.html
And there's still the fun restriction of XFS not being able to shrink. It's not particularly important in the server case, but in the desktop/laptop case, it happens enough in my experience that I'm not sure I'd want a default filesystem that can't shrink.
What about putting it on top of a thin-LV then ? With over provisioning you could even share space efficiently between root & home and would get other features such as efficient CoW snapshots.
Of course as with any thin-provisioning you are also giving up things, such as easily finding out how much free space is actually available to a given storage volume.
