Some do. Some believe that IBM didn't go far enough.
What I miss most is the inability to recover erroneously scratched
members. More than once I have recovered a member that was too new to be

VSAM keeps chains of free blocks, and an option of queueing released
blocks at the end of that chain would have preserved that, at possible
cost (then) of performance.
