Maybe. Have the issues which made XFS less suitable for use on laptops been resolved? 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
As we discussed on IRC, I think idle filesystems won't get these wakeups; if this is still a concern, investigation of the actual effects on battery life (if any) are recommended.
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.
XFS realistically is not going to get shrink. Fedora will need to decide if the other capabilities & features outweigh the lack of shrink capability.
