I also do this, even with Unix fs. Reasons:

fine, but I'd not bet that the file system does not start to
"bit-rot". I have definitely seen this with reiserfs in the past.
* "rm -rf /media/foo/*" is often much slower than "mkfs.xfs /dev/sdb1"
so if I'm going to erase everything anyway, I can also mkfs.
* file system block allocation patterns might degrade over time. Doing
mkfs really starts from scratch
* depending on what was on the disk, I need to dd /dev/urandom onto it,
so a mkfs is needed afterwards.

(yes, i know that urandom -> disk is not enough in general, but it is
usually enough for my use cases)

I know windows admins at a minimum reformat external media routinely.
