We do only set ext4 and BTRF for automatic partition modes to keep it simple, and we do not see any huge benefit on other filesystems.
And you know? adding BTRFS was already causing a lot of trouble for new users attracted by the smell of fresh and fancy Butter.
I know XFS is currently the fancy one again, after users got issues using BTRFS the trend changed a bit.
Afaik the true benefit for XFS is when multiple storage devices are used in combination (p.e. RAID) ?
But that’s just my personal view:
For the manual partition option, you can use all formats as you like already.
But Calamares is a work in progress, manual partition misses an option to add resume, it still can not handle subvolumes for BTRFS fully, LVM support is very limited e.t.c. same for the swapfile option not available in manual partitions and on automatic ones only as one option that adds a 500MB swapfile as it is no resume available.

It is only a minute of work to add XFS but I will not add it only because one user ask for it.
Starting a POLL? or see how many will join here ?
we can have a decision on that.
