Well tested here:
# grep U .bash_history | head -1
tune2fs -U random -L p20deb12 /dev/sda20
# grep U .bash_history | wc -l
42
#

Another PC:
# grep U .bash_history | wc -l
34
# grep U .bash_history | head -1
tune2fs -U random -L p13trixie /dev/sda13

I've been getting rid of 128 byte inode filesystems lately in long term prep for
2038 32bit time rollover.
