The usual cannot-learn-from-the-past reason. Compression costs ongoing
CPU, which is now generally more expensive than memory. But there is
still some resistance to "wasting" memory and/or DASD space. It made
sense in the past. It is senseless now.

BTW - somewhat on the same page, why should anybody use any kind of
compression which uses CPU today? I.e. why do people use DFSMS
compression or some other OEM compression such as BMC's Data
Accelerator? We use the latter, but mainly because we needed to store
more records within the then-existant 4GiB barrier on VSAM.
Unfortunately, the then-management then mandated using it on most
everything in order to defer a DASD upgrade. Now, we are stuck with it
and it is becoming an administrative nightmare. We "compress" files
which then get messages about the files not being compressable because
there exists an alternate index field towards the end of the record.
Sheesh.
