Don't know if this is a regression from before, since in the RHEL 5/6 days I used XFS filesystems as my default filesystem on large storage-pools. Since XFS doesn't have a shrink option, I would create filesystems of a few gigabytes in size, and grow them whenever needed. I mostly used them for monthly archiving of uploads to a customer's website, so there would be a YYYY-MM lvm volume with an XFS filesystem, and during the month it would be grown automatically from a cronjob if space got tight. I'm quite sure I must have had a bunch of full filesystems there, and never ran into any crashing issues with full XFS filesystems (though these were not the 'root' filesystem). But even on my current laptop (with debian 12/13) I'm running XFS on all filesystems (besides /boot and /efi), and they report being full often enough without any crashes/reboots.
