Do you have something that I can cite for that, preferably something that all wiki readers can look at?

All VSAM datasets including Linear are formatted when created. The disk space used is not allocated to any other datasets. Previous data left by deleted datasets is usually left in place (erase on delete is an option but not used frequently) but frequently overwritten in a short time so restoring a deleted data set is almost always impossible.
